Backend API Development (FastAPI/Python)Khadija Subhani
I design and build clean, production-ready REST APIs using FastAPI and Python.
What I offer:
RESTful API development — well-structured endpoints, proper request/response validation, and clear documentation (Swagger/OpenAPI)
Database integration — PostgreSQL schema design, query optimization, and efficient data modeling
Authentication & authorization — OAuth, JWT-based auth flows, secure session handling
Third-party integrations — payment gateways, cloud storage, external APIs
I built the complete backend for AskRAG (a RAG-based Q&A system) and Synapse (an AI-matching platform), handling everything from schema design to deployment. I write code that's not just functional but maintainable — clear structure, proper error handling, and documentation that makes sense to whoever picks it up next.
Whether you need a new backend built from scratch or an existing API cleaned up and optimized, I'll bring the same care I put into my own projects.
