Docker is an open-source platform used by developers to create and deploy distributed applications. Docker is the software that helps automation of deployment of applications in one or more machines. By using Docker, developers are able to separate their applications into isolated containers, which carry with them only the requirements needed to packages the application. This process is then referred to as containerization.
Put simply, a Docker Developer is a programmer specialized in developing applications for the Docker system or environment. With the help of Docker it’s easier for developers to maintain, deploy, and run their applications on any platform from any computer with access to internet.

I am building an end-to-end Python solution that automatically ingests, processes, and reports on financial data pulled from CSV files, SQL databases, and live APIs. Clean, well-structured, and easily maintainable code is essential because the system will be extended over time. Scope of work You will take the project from initial design through deployment. That includes setting up the data-collection pipeline, writing transformation and analysis modules, implementing robust error handling and logging, building unit / integration tests, and preparing a production-ready deployment script or container. The stack is entirely Python, so I expect idiomatic use of tools such as pandas, SQLAlchemy, asyncio, and, where it adds value, lightweight AI/ML components for anomaly detection or forecast...
I have a Python-based, Dockerised service that collects public records from an online government portal. The crawler currently suffers from queue-handling bugs and occasional container issues, so the first milestone is to stabilise the existing codebase and make the scraping run end-to-end again. Once stability is restored I want solid quality gates in place: • Write and wire up full e2e tests that spin the stack in Docker, hit the target site and verify data is written to our queues/storage. • Manually exercise the run, capture a short screen recording that shows the scrape completing and records being persisted. • Wrap all work in a clean Git workflow—open a feature branch, commit changes and raise a pull request so the diff is easy to review. The portal uses a...
I need a straightforward yet rock-solid trading bot that can live on Binance around the clock. The core logic is a 100-level grid: as price drifts down it should accumulate positions level by level, then release them automatically on the ascent to the next level up. Everything has to flow through the official Binance API with secure key handling, low-latency order placement and sensible error recovery. Code & stack • Please write the bot in Python; that is my firm preference because I already use Python for other automation tasks and want to read or tweak the logic later. • Clear, modular structure and comments are important so maintenance is easy. Pairs & strategy tuning I do not have fixed trading pairs in mind and would value your market insight. Feel free to reco...
I need a lightweight web application that keeps my fee records perfectly in-sync with an existing Google Sheet. The app must let me, as the sole Admin, log in through Google OAuth, view all incoming payments, mark them as received, and automatically push every change back to the sheet in real time. Core workflow I expect • Payment tracking – show current balances pulled from the sheet, allow quick status updates, and store a full change log. • Automated reminders – send scheduled email notifications to any payer who still owes fees, using data in the sheet to determine amount and due date. • Detailed reporting – generate monthly and ad-hoc summaries (total collected, outstanding, overdue) that I can download as CSV or view in the browser. Tech f...
I’m spinning up a production-grade content-generation platform and need an experienced Python engineer to own the build from model integration through cloud deployment. The core of the system will combine Agentic AI workflows with Retrieval-Augmented Generation, all running on Hugging Face Transformers and exposed through well-designed APIs. Here’s the flow I have in mind. A user submits a brief, the system retrieves supporting knowledge from a vector store, an agent chain crafts the prompt, and an LLM returns polished copy. Everything must be containerised, orchestrated as microservices, and pushed to Microsoft Azure—ideally AKS with CI/CD in place. FastAPI, async Python, Docker and Terraform/Bicep (or an equivalent infra-as-code tool) should feel second nature to you. ...
I have a brand-new Windows 11 Server where both Docker Desktop (latest stable release) and LM Studio are freshly installed. Everything launches, yet containers inside Docker cannot reach the internet and LM Studio obviously inherits the same limitation. I need the networking issue diagnosed and cleared so standard pull / push commands, package installs and external API calls work without manual proxies or work-arounds. Once connectivity is solid, I would like LM Studio configured for simulation tasks only—no production workloads. Please audit the machine’s CPU, GPU and RAM, then recommend and load the most suitable local AI model so I can start running research simulations straight away. You will receive full Remote Desktop access; I’ll stay on standby for firewall tw...
I’m building a modern, scalable web platform and need a developer who can take the lead on the React.js front end while still speaking the language of a Java/Spring Boot back end. Your main focus will be crafting a clean, responsive interface—complete with custom animations and intuitive interactions—then wiring it seamlessly to our APIs. Here’s how I picture the collaboration: • Front end: Design and code React components that work flawlessly on desktop and mobile, respect accessibility guidelines, and feel smooth thanks to well-placed animations and transitions. • Back end touchpoints: When the UI needs data, you’ll help create or refine the necessary Spring Boot REST endpoints, handle authentication/authorization flows, and jump into performanc...

Project Overview I am seeking an experienced full-stack developer or small team to audit, improve, secure, and modernize an existing production website and infrastructure. This is **not a greenfield project**. An existing frontend, backend/API, PostgreSQL database, content, media, forms, administrative functionality, Docker deployment, and VPS environment are already in place. The current website has experienced intermittent outages and loading failures. Based on prior troubleshooting, the likely problem area is a combination of deployment/runtime stability and security rather than a simple frontend bug. Known symptoms/issues include: Website sometimes hangs or times out while Docker containers still appear to be running. Nginx and Docker are functional, but the deployment is not yet ...

Instead of manually digging through dozens of scattered government portals, users either chat naturally ("I'm a 24-year-old farmer from Maharashtra earning ₹80k/year") or fill a quick profile form (age, income, caste, gender, profession, state), and the app returns matched schemes — PM Kisan, Ladki Bahin Yojana, Ayushman Bharat, PMAY, scholarships, pensions, etc. — with an AI-generated, plain-language explanation of why each one applies to them. Architecture React 19 + TS Frontend (Hugging Face Spaces / Render, Nginx+Docker) ↓ HTTPS Cloudflare Worker (edge gateway) ↓ ASP.NET Core 8 Web API (Railway/Render, Docker) ↓ PostgreSQL (Neon) — 4,600+ schemes aggregated from 5 govt data sources Key features - Conversational...
I’m expanding my tech-education channel and I need clear, engaging tutorial guides aimed squarely at beginners. To start, I want three step-by-step guides covering: • Cloud computing basics • An introduction to AI • Getting started with Docker Each guide should break concepts down in plain language, walk readers through hands-on examples, and finish with a concise recap or checklist so newcomers feel confident moving forward. Well-structured headings, code snippets that actually run, and simple diagrams are all welcome; feel free to suggest the best visual format and any open-source tools that can help illustrate a point. Tone matters here—friendly and encouraging, never dense or academic. If these first guides land well, I’ll likely commission fol...
I need a solid PostgreSQL-backed RESTful API to drive the Solar TwinPro web application. Your task is to design the database schema and expose clean, versioned endpoints that cover full CRUD functionality for each core resource in the system. The web front-end will consume JSON, so consistent status codes and clear error handling are important. Please structure the project so it can be deployed easily (Docker preferred, but I am open to other simple approaches) and include concise documentation; an OpenAPI/Swagger spec is ideal so the front-end team can plug in without guesswork. Deliverables • PostgreSQL schema (DDL) and seed data • REST endpoints covering create, read, update, delete for all defined entities • Environment and run instructions (e.g., Dockerfile or...

I need an experienced engineer who can take ownership of a large-scale, long-term product built around a .NET 8 / ASP.NET Core backend and a React.js + TypeScript frontend. Your first focus will be refining and extending our existing API layer, modelling new features, optimising performance, and making sure every endpoint is production-ready. Once the backend foundations are solid, you’ll move fluidly into the React codebase—building reusable components, wiring state with modern hooks, and ensuring the UX feels instant even when we lean on complex business logic. We already run in AWS, so you should be comfortable deploying microservices and event-driven workflows with containers (Docker) orchestrated through Kubernetes and managed via standard CI/CD pipelines. The infras...
I have a production-bound platform that spans a Django backend, a Vue.js front end, a WordPress marketing site, native Android / iOS apps and several AI pipelines. I now need a technical lead who can jump in and push the remaining pieces over the finish line. Primary hands-on focus • Strengthen and extend the Django REST backend, ensuring it cleanly exposes services consumed by the mobile apps and Vue interface. • Stand up and theme the WordPress instance so it lives side-by-side with the main site while sharing authentication and analytics. AI scope The vision component relies on TensorFlow. You will refine datasets, retrain the model, and package it for inference. OpenCV utilities are already wired for real-time image preprocessing; tuning and optimisation will be par...
We are looking for an experienced Senior Full-Stack Developer to build a browser-based 3D modeling and AI-powered creation platform inspired by Womp.com. This is not a standard website. The platform will include an interactive 3D workspace, real-time browser rendering, AI or GPU-powered processing, project management, and 3D file import and export.

I’m building a computer-vision layer that can reliably recognise images and return structured results that the rest of my platform can consume. The core of the project is an AI-driven image-recognition model; I need someone who can take it from dataset preparation all the way to a callable endpoint. Here’s what success looks like for me: • A well-architected model (TensorFlow, PyTorch or comparable) trained on the dataset I’ll supply—or augmented with open-source sets you recommend—to reach an agreed accuracy threshold. • Clean, readable Python code with clear comments and a short README so future team members can retrain or fine-tune the model. • A lightweight API or Dockerised service that I can spin up on AWS/GCP and hit with a POST requ...
We are building a robust, production-grade automated fulfillment and pricing engine for an store. We have already designed the system architecture, business logic, and error handling rules. We need an experienced backend developer to implement the code quickly and cleanly. DO NOT APPLY if you only know standard web scraping (Selenium/BeautifulSoup) or basic scripts. We need a developer who understands asynchronous Python architecture, state machines, API authentication flows, and queue-based order handling.

Manage persistent seller sessions with dynamic token refreshing, automated retries, and s...
I’m kicking off a 3–6-month enterprise AI initiative on Azure and need an expert who can take charge of everything Databricks-related. The immediate focus is data processing and ML workflows: you’ll stand up and tune clusters, build out end-to-end ETL pipelines, and craft scalable, repeatable machine-learning jobs that flow smoothly into production. Beyond the build, I rely on you to keep the lights on. Our platform runs 24/7, so swift, senior-level ticket resolution is critical—whether it’s a misbehaving notebook, a flaky job, or a performance bottleneck inside a Spark cluster. You should be perfectly comfortable navigating Azure services, AKS/Kubernetes, Docker, and Python/PySpark, bringing best-practice CI/CD and full MLOps rigor to the table. Key deliver...
Our stack runs on a mix of Proxmox VMs, bare-metal Linux, and Docker containers that host several resource-intensive workloads (WordPress sites, small AI services, internal tools). Performance has started lagging, so the goal is a measurable speed-up across the board—CPU, memory, disk I/O, and network throughput. Scope of the optimisation • Server side: fine-tune Proxmox (kernel parameters, storage back-ends, CPU pinning) and harden the underlying Linux hosts, making sure Docker containers inherit those gains. • Network side: analyse current routing, bridges, VLANs and SDN overlays, then remove bottlenecks and reduce latency between VMs, containers and external clients. • Application side: profile the heaviest WordPress and AI containers, tweak PHP-FPM, databas...
I already run a self-hosted Chatwoot instance and now want to turn it into a polished, Respond.io-style omnichannel platform that I can white-label for clients. The work is three-fold: • UI/UX – Give the dashboard layout, chat interface and user-settings pages a modern SaaS look, ensure full responsiveness, and add an easy switch for brand colours, logos and custom domains. • Integrations – Build native connectors for the major social media channels, hook the inbox to popular CRMs, and open the door to additional third-party messaging apps through API/webhook-based plugins. All integrations must be selectable from an admin panel with minimal setup steps. • Extra features – I’d like role-based permissions, advanced reporting, smart routing/a...

I’m looking for a seasoned DevOps mind to streamline my GitHub-based CI/CD workflow and tighten the security of a handful of Linux servers. On the CI/CD side, everything lives in GitLab. I need practical guidance on structuring ., optimising runner usage, and setting up automated staging-to-production deployments with roll-backs and clear version tagging. If you have shortcuts for caching, parallel jobs, or environment-specific variables, even better. The servers behind those pipelines also need attention. Your job is to harden them—from SSH policies and firewall rules to OS-level patching and intrusion detection—so they’re production-ready once the pipeline pushes new code. Deliverables • A working, documented GitLab CI pipeline that builds, tests, and depl...
