FastAPI Jobs

I’m building a desktop-first retrieval-augmented generation (RAG) tool and I need a senior Python engineer to take full ownership of the document-ingestion layer. The current prototype already embeds and queries local language models, but the pipeline that feeds them is still thin. Your focus will be to ingest and normalise three document types—plain text, PDFs, and Word files—so they can be chunked, vectorised, and indexed reliably. Here is the landscape you’ll be stepping into: • Stack: Python 3.11, LangChain, FastAPI, SQLite for local mode, Postgres in the cloud, Git for workflow, and a mix of GGUF local models plus an OpenAI fallback. • Environment: Windows is the primary target, so you should be comfortable with PyInstaller or similar packaging to...

# Python Trading Systems Engineer Needed — Debug Zerodha Live Option-Premium Feed and Paper Trade Monitoring ## Project Overview I am developing an options trading platform using Python, FastAPI, Zerodha Kite Connect, and a modular trading backend. The platform includes a market-data pipeline, instrument repository, option tick store, strategy engine, and paper/shadow trade execution and position monitoring. I need an experienced Python backend engineer with practical knowledge of real-time market-data systems and event-driven trading applications to diagnose and fix an intermittent issue in the existing codebase. **This is an existing-system debugging project, not a complete platform rebuild.** ## Problem Statement The Zerodha WebSocket feed receives option-market data, and t...

At LOW Budget. New Freelancer Needed. I have a set of web-based features that span a PHP back-end and several companion Python services. Some parts still need to be built from the ground up, others need refactoring, optimisation and thorough bug-fixing so the two languages cooperate smoothly. There is no fixed framework mandate yet; clean, well-tested code matters more than the tool choice, so we can decide together whether Laravel, Symfony, FastAPI, Flask or another stack best fits each module after you review the current repository. The deliverable for each milestone is a working, version-controlled slice of functionality with unit tests, clear inline documentation and a short deployment note so I can reproduce your results on the production server. Frequent Git commits and concis...

I need a locally-hosted AI automation platform whose single, clear purpose is to boost day-to-day business efficiency. The focus is on automating order-processing steps that currently slow us down and on intelligently handling the customer information those orders generate. The core workflow I have in mind is simple: an order comes in, the platform captures the associated customer details from our database or front-end form, routes the data through an AI layer that validates, enriches, and formats it, then posts everything back into our ERP with minimal human input. The result should be faster turnaround, fewer manual touchpoints, and cleaner data. You are free to choose a tech stack that makes sense—Python, Node.js, FastAPI, or similar server frameworks alongside an ML compone...

# Build a Higgsfield AI Alternative – AI Image & Video Generation Platform (Ollama, OpenRouter, Multi-API Integration) **Project Type:** Full-Stack Development / Artificial Intelligence / Generative AI **Skills Required:** Python, React.js, , Node.js, FastAPI, Generative AI, Ollama, ComfyUI, Stable Diffusion, API Integration, AI Video Generation ## Project Overview I am looking for an experienced AI developer or development team to build a fully functional, self-hosted AI image and video generation platform inspired by **Higgsfield AI ()**. The goal is to develop a powerful, modern, user-friendly platform that provides similar creative capabilities to Higgsfield while allowing me to use **local AI models, free APIs, paid APIs, and third-party AI providers**. I do not want t...

I’m expanding our product team and need a backend specialist who can dive straight into our Python codebase, extend our microservices, and keep our PostgreSQL layer healthy and performant. The role is fully remote, part-time, and highly collaborative; daily stand-ups, pair sessions, and code reviews are the norm, so you must be comfortable communicating fluently in Portuguese or Spanish. Our current stack centres on Python 3.x, FastAPI, Celery, Docker and Kubernetes, all wired up to PostgreSQL. Your day-to-day work will involve designing and refining REST / gRPC endpoints, improving test coverage, optimising SQL queries, and ensuring smooth CI/CD releases. Every two-week sprint you’ll own a set of stories, ship merge-ready PRs, document your changes, and jump into peer reviews...

Job post Senior AI / Full-Stack Engineer — Education Intelligence Product (Part-time / Project initially) I am building an AI-powered mathematics learning intelligence product for students, parents and teachers. The core intelligence/backend already exists and is being actively developed. I am looking for a strong engineer to help turn the existing system into a robust working product—not to build a chatbot wrapper from scratch. Initial scope The first phase is focused on building and polishing: - Parent/student conversational chatbot - natural multi-turn conversations - understands context and follow-up questions - grounded entirely in student records - evidence/verification behind answers - conversation persistence - Student intelligence - performance and learning...

I need production-ready software that proves out the latest frontier-model capabilities from end to end. The work spans everything from designing the data layer to wiring up sleek UIs, then packaging and deploying so that real users can click around and see the model in action. You can reach for the stack that lets you move fastest—Python/Django or FastAPI, Java/Spring Boot, TypeScript/Node.js or , even Rust, C#, or modern C++. Cloud services (AWS, Azure, GCP) and containerisation with Docker/Kubernetes are welcome if they speed delivery; I’m flexible as long as the final result is easy to stand up and maintain. Frontier-model features sit at the heart of each build. Whether it’s natural-language understanding, computer-vision pipelines, data-driven recommendations, or ...
