Avtar S
About this gig
Need a fast, reliable Python backend built by a senior engineer? I bring 9+ years building production APIs and cloud systems for high-traffic products.
WHAT I BUILD:
- REST APIs with FastAPI (or Flask/Django) - clean, documented, and tested
- - PostgreSQL / MySQL / ClickHouse database design and integration
- - Authentication (JWT/OAuth), input validation, and solid error handling
- - Async tasks, background jobs, and third-party API integrations
- - Dockerized apps with CI/CD and AWS deployment (Lambda, ECS, EC2)
WHY ME:
- Real production experience: cut API latency 45%, scaled analytics 10-100x
- - Clean, maintainable code with automated tests and clear documentation
- - Clear communication and on-time delivery
Every order includes source code and a setup guide so you can run and extend it easily.
Not sure which package fits? Message me first with your requirements and I will recommend the right scope and can send a custom offer. Let's build something solid.

FAQ
Which Python framework do you use?
Primarily FastAPI for its speed and automatic docs, but I also work with Flask and Django. Tell me your stack and I will match it.
Will I get the source code?
Yes. Every order includes full source code, a setup guide, and clear comments so you can run and extend the project yourself.
Can you deploy the API to AWS or my server?
Absolutely. I can Dockerize the app and deploy to AWS (Lambda, ECS, EC2) or your preferred host, with CI/CD if needed. Included in Premium or as an add-on.
