I’m bringing a new hardware brand to market and need a complete mobile operating system built from the ground up, ready for both smartphones and tablets at launch. Everything must feel effortless for everyday consumers: smooth onboarding, clear navigation, and responsive gestures. Security is just as critical. I want encryption, robust permission management, and an architecture that protects user data by default. At the same time, the interface should welcome personal style—theme packs, flexible layouts, and other custom options that never compromise stability or safety. Key objectives • Deliver bootable images for reference phone and tablet hardware, plus a reproducible build environment (AOSP, Linux kernel, or comparable stack is fine if it accelerates delivery). ...

I need a seasoned development partner who can take this project from architecture through deployment: a fully-featured, web-based Hospital Management System that scales smoothly, protects sensitive data, and is intuitive for everyday medical workflows. Core functionality must cover • Patient record management with searchable, role-based access • Real-time appointment scheduling linked to individual practitioner calendars • End-to-end billing and invoicing that supports multiple payment methods and insurance claims Although doctors, nurses, and other clinical staff will use the back-office side most heavily, patients also need their own secure portal to view records, book or change appointments, and settle bills online.

SuperLink ISP CRM is designed to manage ISP operations from a centralized platform, including customers, sites, network connections, tickets, billing, payments, credentials, quotations, and operational workflows.

I need a production-ready AES implementation that I can drop into our stack to protect data at rest. The focus is on clean, well-documented source code that supports 128, 192, and 256-bit keys, CBC and GCM modes, plus straightforward hooks for key rotation. My environment is a mix of Python micro-services and a Java back-end, so a portable C/C++ core wrapped for those languages—or native, equally secure versions—would work. What matters most is that the code passes standard NIST test vectors, includes unit tests, and ships with a concise integration guide. Deliverables: • Fully commented AES library (source + build instructions) • Test suite confirming compliance with FIPS/NIST vectors • Short README covering integration and key management reco...

I’m ready to add a simple, effective defence against bots on my site and need a developer to build a custom, case-sensitive text captcha. The challenge text should be visually protected by smooth wavy-line distortion so humans can still read it at a glance while automated scripts struggle. Here’s what I expect: a compact module (plain PHP, Python, or JavaScript—whichever you’re most comfortable with) that generates the image on the fly, validates the visitor’s input on form submit, and lets me tweak essentials such as character length, font family, colour palette, and distortion strength through a few easy constants or settings. The code has to slot neatly into an existing page without extra frameworks, and I should be able to drop it on multiple forms after ...
I need an end-to-end Android finance application that is bullet-proof from a security and compliance standpoint. The core flow begins with a smooth, secure onboarding experience that performs Basic KYC checks; I’ll supply the exact compliance rules and the API endpoints you should call. Once a user is verified, the app must display real-time account balances and a transaction history that includes fast search and filter options. If you’d like to suggest richer breakdowns or export features later, I’m open, but they’re not part of the first release. Security requirements are strict: data must be encrypted at rest and in transit, all sensitive actions gated by biometric login (Android BiometricPrompt), and every meaningful event captured in an immutable audit trai...

I’m ready to bring a full-featured medical tourism platform to life and need an experienced team or individual who can take the idea from concept to launch. The core goal is to let prospective patients discover qualified healthcare providers abroad, understand treatment options, and complete every step—from inquiry to confirmed appointment and travel logistics—inside a single, secure environment. Here’s what I expect: • A modern, responsive web application with intuitive patient and provider flows. • A secure backend that can scale as traffic grows, built on a technology stack you’re comfortable supporting long-term. • Essential modules such as provider profiles, treatment listings, real-time availability, booking management, payment p...
I am rolling out a new Identity Governance initiative and need an engineer who can take full ownership of the solution design and deployment. The core of the engagement is Identity Governance—specifically rock-solid Role Management, airtight Compliance and Audit reporting, and automated User Lifecycle Management. My environment is hybrid, so you will be connecting on-premises directories and systems with our cloud workloads. Expect to work with common IAM stacks (SailPoint, Saviynt, Azure AD, Okta, or similar) and the usual supporting tech—PowerShell, REST APIs, and modern authentication protocols (SAML, OAuth2/OIDC). What I need from you: • Assess the current hybrid identity landscape and document gaps. • Design an end-to-end governance model covering roles, acce...
I am launching an online “rental boyfriend” service and need both a responsive website and companion iOS/Android app built from the ground up. The core of the product is a smooth booking system that allows customers to reserve time slots with their chosen companion and automatically sends booking reminders (push, email, or SMS—whatever is easiest to wire up). Here is what I have in mind: • Cross-platform build – a single code-base approach such as Flutter or React Native is welcome, so long as the end result is a fast website and native-feeling mobile apps published to the stores. • Clean UX – browsing available companions, selecting a date/time, and checking out should happen in just a few taps. • Booking engine – real-time availabi...
I need a developer who can take this accounting workflow out of spreadsheets and into the cloud. The core of the job is to deliver a web-based platform hosted on Firebase, with data stored and transmitted securely. What the application must do • Let me spin up unlimited “companies” so each business keeps its records completely separate. • Provide simple Email-and-Password authentication for every user role. (If you think we should layer OAuth or 2FA later, keep the codebase ready for it.) • Offer a clean UI where I can create customers, assign them to groups, and then post two entry types—Payment or Journal Voucher. • For each entry I’ll input debit, credit and a narration; the system automatically stamps the exact date-time and shows ...
I’m ready to connect my Lovable account with GoHighLevel but need an expert to handle the technical details from end to end. The main outcome I’m after is a secure, fully-functioning integration that issues Encryption keys for public use so outside services or landing pages can tap into GHL without exposing any sensitive data. Here’s the flow I have in mind. Once the two platforms talk to each other, the system should automatically generate and surface a public-facing key pair while keeping the private component locked away. Although my immediate priority is getting those Encryption keys live, I’m open to expanding the build later to include contact management, automated email sequences, or sales-funnel tracking once the core connection is stable. You’ll hav...
