FastAPI Jobs

I am building a full-scale algorithmic trading platform and need an experienced developer to take it from concept to production. The core of the system will execute three distinct strategies—scalping, day trading, and swing trading—running side-by-side from a single codebase. The app must pull real-time market data and place live orders across all major asset classes, so please factor in direct integration with: • Stock market APIs • Cryptocurrency exchanges • Forex market feeds Key expectations • Low-latency data capture with WebSocket or equivalent streaming. • Strategy engine that can be toggled per asset, with configurable parameters and risk limits. • Unified order-routing layer capable of handling spot, margin, and conditiona...

The developer should build a cross-platform AI-powered IT Help Desk agent and management system that supports Windows, Linux, and macOS. The system must include a backend API (preferably in Python FastAPI or Node.js) to handle ticket management, device registration, and command distribution, along with a secure database (PostgreSQL) and an optional vector database for AI knowledge retrieval. The agent itself should be written in a compiled language like Go for cross-platform deployment, capable of registering devices, reporting system info and heartbeat, detecting missing patches, restarting services, and executing safe commands remotely. The AI component should analyze incoming IT tickets, automatically suggest fixes, and optionally execute auto-remediation commands when safe. All communi...

Project Overview We are looking for a developer to build and integrate a professional AI chatbot for our platform, Proxima Study. The goal is to allow students to ask questions on the front-end and receive answers generated by leading AI models (ChatGPT and Gemini) through a secure back-end bridge. Scope of Work Chat Interface (Front-end): A clean, user-friendly chat bubble/window on our website where students can type questions. It must support "streaming" (where text appears word-by-word) so users aren't waiting on a loading screen. The Bridge (Back-end): Develop a secure middleman (API) that takes the student’s question, sends it to OpenAI or Google Gemini, and brings the answer back to the website. AI Logic: Set up the system so I can easily toggle which AI mode...

Please read carefully before bidding. We are building a production-grade AI-powered building inspection report platform. 90% was built in base44 however, base44 cannot parse pdf"s larger than 10MB, so we have hit a roadblock and decided to take another route. This is NOT: *A WordPress job *A Shopify job *A bubble/no-code job *A “prompt engineering” job *A basic CRUD web app This is a serious backend architecture project involving: PDF parsing (11MB+ technical reports) AI defect extraction Structured data normalization Repair cost estimation logic Long-running job orchestration Background workers / queues Multi-user concurrency Production deployment architecture NOTE: Required Technical Stack (Non-Negotiable) You must have experience with: Node.js or Py...

I need a professional market intelligence tool for MercadoLibre Venezuela (MLV). The goal is to track competitor sales by monitoring inventory changes (Inventory Differential Tracking).

Output: Data synced to a Google Sheet.

I’m ready to move beyond notebooks and actually ship models, but I’d like to do it the right way, step by step, with an expert by my side. My stack of choice is Python, and we’ll be working on Google Cloud. The part I’m most eager to master is model serving and building production-grade APIs, though I still want you to frame everything in an end-to-end workflow so the pieces fit together. Here’s how I picture our work together: • Pair-programming sessions where we containerise a trained model, push it to Google Cloud (e.g., Cloud Run or Vertex AI), and expose it through a REST or gRPC endpoint. • Walk-through of best practices for versioning, environment management, and automated CI/CD so each new model can be rolled out with minimal friction. ...

I’m building and maintaining a series of backend services and I need an experienced Python developer who feels at home in FastAPI. The day-to-day work centres on designing clean, scalable REST endpoints, wiring them to a PostgreSQL database, and keeping the Dockerised environment tidy for smooth deployments. Most of the upcoming tasks involve integrating external providers: think payment gateways for transaction flow and AI/ML services that power in-app intelligence. Beyond those, you’ll help craft automation scripts, refine existing business logic, and keep an eye on performance as traffic grows. Here is what a typical assignment looks like: • create or extend a FastAPI micro-service • expose secure endpoints, including user auth where required • conne...

I need a seasoned backend developer to design and implement a secure REST API that lets my users check award-seat availability (Avios) directly from Iberia.com. The core of the job is to automate the full search flow — login, query, filter, and return the results — while keeping the service fast and reliable. Authentication & security The service must issue and validate JWT tokens for every request beyond the public health-check route. Token refresh, revocation, and a simple role model (“user” vs. “admin”) should be built in from the start. Flight data extraction I do not have official Iberia developer access, so we will need to pull the data ourselves. I’m open to whichever tooling you are most comfortable with — BeautifulSoup, Sel...

Seeking an experienced full-stack/ML developer to build a secure, cloud-based web platform for analyzing anonymized dental X-rays. The tool enables upload of DICOM files, automatic anonymization (strip all metadata/identifiers), AI-driven detection & annotation of pathologies (caries, periodontal disease, bone loss, cysts, etc.), visual overlays, confidence scores, and report generation—all with strict patient privacy, no storage of originals, and human oversight required. Key Requirements: • Clean React/ frontend with drag-and-drop upload, DICOM viewer (e.g., ), annotation overlays & heatmaps. • Python backend (FastAPI preferred) + secure auth, encrypted file handling, and cloud storage (AWS S3/GCP). • PyTorch/TensorFlow ML models (fine-tune YOLO/U-Net/M...
