I will build and integrate rest apis using flask and fastapi


About this gig
Need a fast, secure, well-documented REST API or help connecting your app to third-party APIs? I build backend systems using Flask and FastAPI that are clean, scalable, and production-ready.
I've worked on healthcare and research-domain web applications at a university research lab, building APIs that handle real data, real users, and real reliability requirements not just toy projects.
What I can do for you:
- Design and build REST APIs from scratch (Flask/FastAPI)
- Integrate third-party APIs (payment gateways, CRMs, external data sources)
- Connect your API to MySQL, PostgreSQL, or MS SQL Server
- Add authentication (JWT/OAuth), rate limiting, and input validation
- Write clear API documentation (Swagger/Postman)
- Dockerize your app for easy deployment
Tech stack: Python, Flask, FastAPI, Django, MySQL, PostgreSQL, Docker, REST, JWT
- Let's discuss your project send a message before ordering if you have custom requirements.
