I have already gathered the required DNS values from my host, Here is what is ready on my side: * Full Cloudflare access (zone and DNS tab) * The exact DNS settings the host provided for the site that should sit behind the subdomain What I need from you is straightforward: log in, create the subdomain, plug in the correct record, double-check proxy status, and confirm it resolves publicly (I will test with a browser). A quick screen capture or short note explaining the steps would also be helpful so I can repeat the process in the future if I add more subdomains. Once the new name shows live worldwide, the job is done. This should be a fast task for someone who works with C...

I’m running an Apache-hosted PHP page that triggers a Node script () powered by Puppeteer. When I call the PHP page through the browser I hit a generic “Server Error,” yet the very same runs flawlessly from the command line. I need someone who can: • trace why the PHP→Node hand-off fails under Apache but succeeds in CLI, • correct any permission, path, environment-variable, or timeout issue that is blocking Puppeteer, and • leave me with a clean set of notes on exactly what was changed (Apache/PHP config, code tweak, or OS-level adjustment). A working demo in the browser along with the change log is the acceptance criterion. I can provide SSH access and the current PHP and Node files as soon as we start.

I need a reliable engineer who can travel to my client’s office in Pune once a week to keep their servers and desktops fully patched. The role is strictly technical maintenance: every visit you will review the latest releases, schedule any required downtime with the on-prem team, apply software updates and security patches on both Windows and Linux machines, then verify services are back online. Typical stack you’ll touch includes Windows 10/11, Windows Server 2019, Ubuntu LTS and a few CentOS boxes. Experience with Windows Update Services, PowerShell, apt/yum and basic bash scripting will help you move quickly, but I’m happy if you have an equivalent toolset that achieves the same result. Deliverables each visit • All pending OS patches applied successfully &b...
Running RHEL 9 with iptables I can reach , yet any file upload stalls. The traffic is routed through Cloudflare and the service calls several sub-domains, so I’m convinced outbound requests are hitting IP-based restrictions that my firewall is silently dropping. I have not built a whitelist yet and need help discovering every endpoint involved. What I need from you: • Capture and inspect the outbound upload flow—feel free to rely on your own custom scripts for deeper parsing. • Identify every IP address, domain, or CIDR block the conversation touches, including any Cloudflare edges that appear only during the upload handshake. • Propose and implement the minimal iptables changes (or an equally secure alternative) that let uploads complete while keeping the...
I need EspoCRM deployed in two places: first on my QNAP NAS, then as a fresh install on our Gulf eOne server. Both are straight-forward, standard installations—no custom modules or extra extensions at this stage—yet they still have to be production-ready, secure, and fully tested. You’ll handle every step: preparing the environment, creating the required database, uploading core files, running the web-based installer, setting up the cron job, and making sure HTTPS works. Once each instance is live I’d like a short hand-over note that lists the admin credentials you created, paths to key config files, and any tweaks you made for performance or security. Please bid only if you have hands-on experience with EspoCRM on QNAP or similar NAS devices and are comfortab...
I have a website created in wordpress which is running. I need to install an application in a sub domain. However the application requires port 80 / 443 and as per someone its already used by my main domain. Thus I cannot run any other web application in a sub domain. Request you to let me know if this is correct. Basically I need to install and run a web application for kyc system in a sub domain but I do not know if its possible or not. Server OS is CentOS. Apply is you have strong knowledge of web server technologies & server infrastructure.
In ASTPP there is option Grace Time to provide free calls to customers. From https interface go to Tariff - Origination Rates, click on any rate. It has field grace time, which is in seconds. So if I put 600 seconds, then each time someone dials a number with concerned code, 10 minutes must be free. But that option works wrong. Even though there is grace time, it counts how much money customer has. For example, if code 41 costs 0.3 CHF min, and customer has 0.6 CHF on the account, after 2 minutes, the call disconnects, even if the grace time is 600 seconds (10min) for example. Freelancer must find the concerned configuration files and correct it, so that in case there is Grace time for the code in Tariffs - Origination rates, the code must consider the grace time first and then only start ...
I have a cable-modem internet line in Pakistan that I must be able to reach securely from any location worldwide. The hardware on site is a Netgear router that has not yet been configured. Your task is to turn that router into a reliable gateway: load the right firmware (or update the stock one if that is safer), create a VPN server on it and make sure I can tunnel into the network whenever I’m abroad. I chose a Virtual Private Network as the connection method, but I am flexible on the exact protocol—OpenVPN, L2TP/IPsec or any other option you feel will balance security with ease of use. All I care about is rock-solid encryption, stable throughput and the ability to reconnect automatically if the line drops. Once the VPN is up you will also need to confirm that I can log ...

I have a fully-built MERN stack application ready for production and now need it running smoothly on AWS. The core environment will live on EC2, with static assets off-loaded to S3, so you should be comfortable configuring both services for high availability, security groups, IAM roles and VPC networking. Beyond the initial lift-and-shift, I want a hands-free release process. Please set up a full CI/CD pipeline and wire it to my GitHub repo, using Jenkins as the orchestrator. Containerising the app with Docker is preferred so updates remain predictable and rollbacks are easy. Key outcomes I’m looking for: • Production instance online behind a domain, SSL in place and basic monitoring enabled • Automated build-test-deploy pipeline in Jenkins triggered by every push t...
I’m ready to retire my Magento 1 site and relaunch on Magento 2, but I need the move handled end-to-end with zero data loss and minimal downtime. The must-haves are clear: every extension or plugin that powers the current store has to carry over (or be replaced with an equivalent Magento 2 option), and all customer records plus complete order history need to be migrated intact. You’ll be working on a fresh VPS hosting environment, so you’re free to tune PHP, MySQL, Elasticsearch, Redis or any other stack elements as you see fit for performance and security. I’ll provide root access once we agree on the plan. To keep us both aligned, here are the concrete deliverables: • Inventory and compatibility report for all existing extensions/plugins, with recommended ...
My home lab runs on an Ubuntu server and I want Eve-NG fully installed (community version), and ready for advanced network simulations. You’ll connect through my Windows PC which I’ll leave on for you; I’ll keep a PuTTY SSH session open so you can hop straight onto the box. Key things I expect • Eve-NG Community or Pro—whichever fits best for building complex, multi-vendor, “advanced” topologies. • Proper kernel tweaks, nested virtualization settings, and any performance tuners needed so the platform stays stable when I spin up large labs. • Your advice on supplementary tools or packages that make day-to-day lab life easier (Wireshark, Docker helpers, useful Eve-NG add-ons, etc.). If you feel nothing else is required, just let me k...
I have a Dell rack-mount server (Dell EMC PowerEdge R540) that already runs Ubuntu, and I’m ready to convert it into a dual-purpose box for my custom-built web applications. I need Windows Server 2019 or above to be installed alongside the existing Ubuntu installation, with the lion’s share of disk capacity devoted to Windows and a smaller XFS-formatted slice left for Linux. Everything has to be partitioned manually, so you’ll need to be comfortable working in the RAID controller, the Dell lifecycle controller/iDRAC tools, and the Windows installer’s advanced options. Once the disks are laid out correctly I want both operating systems fully bootable, networked, and ready to serve web traffic. The Linux side must remain intact with XFS as its file system; the Window...

I am building out a Cisco service-provider lab and need an experienced CCIE (or equivalent) to walk me through a full VXLAN with EVPN configuration from scratch. The focus is purely on configuration—not troubleshooting or green-field design—so I have the topology ready and gear online; what I lack is the precise, production-grade CLI that ties it all together. You will guide me step-by-step, explain each command’s purpose, and provide verification checks so I can confirm that both Layer-2 and Layer-3 tenant traffic flows correctly over the underlay. We will work live over screen-share; a concise set of notes and final device configs should follow the session so I can replicate the setup later. Deliverables • Live remote session (up to 2 hrs) configuring VXLAN + E...
I have a web application ready in my repository and now need it running in a reliable production environment while the backend is brought online. The immediate priority is to deploy the current build and wire it to fully functioning API endpoints.
I have a fresh Linux-based VPS that must be production-ready as quickly as possible. The job is a straight-forward but time-critical stack installation and configuration: • PHP, Node.js and any supporting packages – I’ll pass along exact version numbers the moment the project starts. • Ollama LLM (olama llm) installed so I can load local language models without friction. • phpMyAdmin tied into the default MySQL/MariaDB instance. • Mailcow running in its recommended Docker layout, fully functional for SMTP, IMAP, webmail and spam filtering. • DNS services set up (either Bind9 on the VPS or clean integration with Cloudflare—whichever you’re more comfortable hardening). • SSL certificates, basic firewall rules and fail2ban so ev...

I want a production-ready FreeSWITCH-based Session Border Controller that registers or peers with my clients’ PBXs by username and password, transcodes to Opus, and then hands the calls off to two preset wholesale carriers. The core logic is: • Country-level routing priorities stored in MariaDB. – Example: US/Canada → Carrier 1 first, fail over to Carrier 2; EU → Carrier 2 first, fall back to Carrier 1 on 404 or no answer. • Each client may present several PBXs and DIDs, all of which must map cleanly to those database rules. • Carrier trunk details stay hard-coded in the FreeSWITCH XML/JSON configs; only the client and route data live in MariaDB. • CDR I also need a small web interface (PHP, Python Flask or a similarly light stack i...

I’m spinning up a new backend and want a hands-on developer who can jump straight into building production-ready, secure APIs. The stack is Node.js with Express, PostgreSQL on the data layer, and Microsoft Graph for several integration points. You should already be comfortable handling OAuth flows and token management because authentication is wired through Azure AD. My priority is robustness: clean, well-documented endpoints, solid error handling, and security baked in from the start. If you have experience tightening Node.js applications against attack vectors, you’ll feel at home here. Please tell me about projects where you built or hardened APIs on a similar stack. I’m particularly interested in how you approached authentication with Microsoft Graph or secured Post...

I need a fresh Linux-based VPS deployed with the latest Ubuntu LTS, fully updated, hardened, and ready to serve websites out of the box. Please install and configure a production-grade web server—Nginx is preferred, but Apache is acceptable if you can justify the choice—along with the usual essentials (UFW or another firewall, fail2ban, swap tuning if needed, and basic SSL readiness with Certbot). Here is what I expect at hand-over: • The VPS is accessible via SSH on a non-standard port with root login disabled and a sudo user created for me. • The web server starts on boot, serves the default site without errors, and is ready for additional vhosts. • All packages are up to date, unnecessary services are removed or disabled, and system time and locale are ...
I run a full-stack Node.js application—separate frontend and backend repos—on an Ubuntu-based EC2 instance. The code lives on GitHub, and right now every update is still being deployed manually. I’d like you to wire everything together through Jenkins so each push to the main branch triggers a clean build and automated deployment to my server. Here’s what I already have in place: an EC2 machine with Ubuntu up and running, SSH access, and GitHub credentials ready to integrate. Jenkins is not yet configured, so you will need to install, secure, and set it up on the same instance (or guide me through a best-practice alternative if that proves wiser). Your work will cover the full build-and-deploy stage only—no test or monitoring jobs for now. I expect a Jenkins...
My dedicated server has begun crashing unexpectedly several times a day, and I have also spotted unknown processes running in the background. These symptoms make me suspect either an active attack or hidden malware rather than a simple configuration issue. I need a seasoned security-minded admin to dive in right away: comb through logs, inspect running services, trace any rogue binaries, and pinpoint the root cause of the repeated crashes. If malicious code or a breach is confirmed, I will rely on you to remove the infection, patch the vulnerability, and harden the system so the problem does not return. Deliverables I can sign off on: • Written report identifying the exact cause of the crashes and all suspicious processes found • Clean-up actions performed (malware removed, c...
We are seeking a highly skilled developer with expertise in Aeron and SBE to engineer a greenfield, ultra-low latency cryptocurrency market-making core on AWS. The goal is to achieve an internal tick-to-trade latency of <50 microseconds (p99) on the "Hot Path." Key Objectives: - Implement a single-server, multi-process architecture where Data Ingestion, Strategy, and Execution communicate via Shared Memory (IPC), bypassing the network stack entirely for internal messages. - Leverage Aeron (for transport) and SBE (Simple Binary Encoding) to eliminate garbage collection and object copying. - Ensure the system runs efficiently on AWS c5n instances with Kernel Bypass and CPU Pinning enabled. Deliverables: The project will be divided into three milestones: 1. Miles...

I’m looking to tighten up email authentication on two separate sender domains by adding fully-compliant SPF, DKIM and DMARC records. I already hold direct access to the DNS zones, so you’ll be able to push the changes—or send me the exact TXT snippets to paste—without delay. At the moment there are no existing authentication records to worry about, which means you’ll be starting from a clean slate. I need you to: • Build and publish a correct SPF record for each domain, keeping it under 255 characters and within the ten-lookup limit. • Generate DKIM keys, supply the private keys securely, and add the corresponding public selectors in DNS, then confirm they sign properly. • Create DMARC policies (initially “none” with aggregate ...
I have a fresh Odoo 16 instance waiting to be brought to life and shaped around solid project management workflows. Your task is to take me from “blank slate” to a production-ready environment that my team can log into immediately. Here’s what I need: • Full installation check and server-side configuration of Odoo 16 • Activation and tuning of the built-in Project app so tasks, stages, timesheets, and milestones feel intuitive for everyday users • Clean permission rules that separate manager and collaborator roles without blocking anyone’s daily work • Basic company data, email aliases, and notifications set up so discussions stay inside Odoo rather than in scattered inboxes • A short hand-off document (or quick video) that shows wh...
My Hostinger VPS is running Linux and has been hit by a Trojan-style malware infection. I need someone who can step in quickly, clean out every trace of the malware, and then lock the system down so it stays secure. Nothing is currently installed for antivirus or anti-malware protection, so you will be starting from a clean slate. The job involves three concrete phases: • Malware removal – run a full scan, identify infected files or processes, and eradicate the threat without disrupting live services. • Security hardening – configure a solid firewall (e.g. iptables/ufw), set up fail2ban or similar, close unused ports, patch the OS and services, and install reputable anti-malware/IDS tools. • Ongoing monitoring – deploy lightweight monitoring so I can ...
I need a lightweight Python script that connects to Gmail’s SMTP server and automatically sends a single “Welcome / Registration Confirmation” email whenever a new user joins my platform. Here’s exactly what I’d like you to handle: • Code the script in clean, well-commented Python (standard smtplib + ssl are fine). • Deploy it on my Hostinger shared hosting account, configuring it through cPanel or a Cron job so it fires reliably. • Test end-to-end delivery with my live Gmail sender account (I’ll provide the credentials and any required app-password). • Leave me with a short README that shows where to tweak the subject line, body text, and any future SMTP settings. Deliverables 1. Complete Python source file(s) 2. Wor...
I have a Dell EMC Networking S4148F-ON destined for a data-center rack, but it is still running the factory shipping firmware. I need OS10 loaded and booting cleanly before it can be placed into production. At the moment I do not have the OS10 image, so part of this job is helping me source the exact, legally obtainable image that matches this model and its license entitlement. Once the image is in hand, you will guide (or remotely perform) the complete installation: preparing the USB or TFTP method, establishing console access, upgrading the boot code if required, and verifying a successful boot into OS10. I am not looking for additional VLAN, load-balancing, or redundancy configuration right now—just a pristine, up-to-date operating system ready for me to configure later. Deliver...
I have three network assignments lined up and I want a CCNP-level specialist in Routing and Switching to take full ownership of them. All work is on Cisco gear—primarily ISR and Catalyst routers and switches—plus the firewalls that sit at the edge. Scope of work 1. Configuration – roll out a fresh router/switch stack, establish VLANs, trunks, and dynamic routing (EIGRP and OSPF) so the new gear drops into production cleanly. 2. Troubleshooting – track down an intermittent routing-loop issue that crops up when BGP fails over, and clear up a STP inconsistency on the access layer switches. 3. Optimization – tighten latency by adjusting path selection, pruning unused VLAN traffic, and tweaking QoS policies affecting the firewalls. Deliverables • Update...
I’m ready to retire my current VPS and move everything—files, databases, email, AdGuard Home, Nextcloud, a mail server, and a couple of smaller services—to a fresh dedicated machine. I also need the custom app built by Caffeine installed and running smoothly once the move is done. The new box is already provisioned; what it lacks are my existing services, their data, and the fine-tuned settings I’ve accumulated over time. That includes every firewall rule, cron job, SSL certificate, and any other tweak that makes the stack hum. The only thing that changes is the IP address, so you’ll need to update references accordingly. For clarity, I’ll sign off on the job when: • All services (web, mail, AdGuard Home, Nextcloud, Caffeine app, plus the few sma...
I have an in-house BACnet/IP data-acquisition connector built with Python and BAC0 that already polls real devices on our test network. Before we can roll it out at scale, I need a Python engineer who can take the code from prototype to production. The priority is to standardise the existing REST-style APIs and iron out the remaining BACnet communication issues—packet timing quirks, device discovery edge cases, and error handling. While doing so, you will also strengthen stability, recoverability, observability, performance and scalability so that the same build runs reliably on virtual machines, bare-metal servers and BalenaOS devices. You will be working directly with our architect and senior developers, have SSH access to the BACnet lab for end-to-end tests, and can inspect the ...
My production mail server runs on Debian and every main layer—Postfix, Zimbra and the Kernel—now needs to move to the latest stable releases. All three components must come through the process with complete data integrity, so the job starts with a solid backup plan: at the moment no backup exists and I will rely on you to design, create and test one before any package is touched. Once the safety net is in place, the work continues with a carefully staged upgrade. Postfix, Zimbra and the Kernel should be brought up to date, followed by migration to the current Debian stable. I expect minimal downtime, full preservation of mailboxes, calendars, contacts, aliases and logs, and a short verification window after each major step to catch issues early. The assignment is finished whe...
I need an experienced developer who already holds at least one AWS Professional-level certification to help me build and deploy an end-to-end natural-language-processing pipeline and AI interpretation. The job revolves around text classification only—no image work or sentiment scoring. You are free to leverage services such as SageMaker, Comprehend, Lambda, and API Gateway as long as the final solution stays fully within my AWS account and follows best-practice security policies. Here’s how I picture the engagement: • a microphone icon is shown during an interpreting session • It interprets two people's conversations without having to press any buttons. If you have the certification and hands-on experience to turn this around efficiently, I’d lo...
I need a clean, production-ready deployment of Virtualizor on my dedicated server. Everything will be Linux-based, and the end result has to feel like a small private-cloud product that I can start selling straight away. Scope • Create three ready-to-sell VPS plans inside Virtualizor, each with its own resource limits and pricing labels. • Activate internal IP addressing so all guests can communicate over a private network while keeping their public interfaces separate. • Integrate PowerDNS and configure reverse DNS records so every new VPS receives valid PTR entries automatically. • Ensure NoVNC consoles open flawlessly in the client panel, with clipboard support and no mixed-content warnings. • Implement advanced firewall rules: custom port mappings, IP-based re...
I need GenieACS installed and fully configured so it can act as my TR-069 ACS for every CPE we ship—routers, modems and gateways alike. Besides a clean installation, the job includes writing any required scripts so that new or unknown devices are auto-detected, properly provisioned and able to report client Wi-Fi status back to the platform. Daily operations have three pillars: device-side firmware upgrades, streamlined configuration management and a solid troubleshooting/diagnostics workflow. I also want built-in visibility, so the system must generate error reports, store connection logs and track usage statistics I can export or view from the GenieACS GUI or API. Deliverables • Production-ready GenieACS instance installed on my server (Ubuntu or CentOS—let me know whi...
My cPanel/WHM box has begun crashing at unpredictable moments. It runs fine for hours, then—without any scheduled backups, updates, or config edits—the Apache service suddenly drops. Each time I check the logs I see a sharp spike in CPU / RAM use right before the failure, but I have not pinned down the root cause. Here is what I need from you: • Diagnose the crash pattern quickly by digging through Apache, cPanel, and system logs. • Optimise and fine-tune the current Apache/WHM configuration (MPM settings, KeepAlive, limits, etc.) so the server can absorb traffic bursts without tipping over. • Apply any kernel, EasyApache, or module tweaks that will stabilise resource usage. • Provide a concise report explaining the cause, the steps you took, and t...
I’m rolling out a large community-wide WiFi network and I want my central MikroTik router configured to serve both hotspot users and PPPoE subscribers smoothly. The goal is a single, well-tuned RouterOS configuration that handles the following: • Hotspot – custom HTML/CSS login page, voucher-based access, per-user bandwidth shaping • PPPoE – reliable user authentication, dynamic bandwidth profiles, and multi-gateway load-balancing for resilience • Consistent bandwidth management across both services so no one user can choke the link I’ll provide remote access to the router along with design notes and branding assets for the captive portal. Once you’re done I’d like a short hand-over document (or quick Loom video) outlining the key qu...
