// 01. about

The person
behind the code.

I'm a Python Backend Developer with 5+ years of experience designing and scaling REST APIs, backend automation, and infrastructure tooling — across the finance and networking domains at Accenture and now Infosys.

I led a production NGINX-to-Envoy load balancer migration supporting 3M+ requests with zero downtime, built Python automation that cut manual effort by 80%, and reduced mean-time-to-detect (MTTD) by ~40% through real-time monitoring tooling. I've also mentored junior developers in Python best practices and test-driven development.

I believe great backend code is invisible — it just works, scales quietly, and never surprises you at 2am. Grounded in a strong DSA foundation and a production-first mindset, I'm looking for a Python backend role where I can keep building systems I'm proud of.

Things I've built.

🔗

URL Shortener

A full-stack URL shortener with a FastAPI backend and React frontend. The API runs as a systemd service via Uvicorn on AWS EC2, with NGINX configured as a reverse proxy serving the React app and routing /api/ requests to FastAPI. EC2 setup and deployment are automated with Bash scripts.
