About

A bit about me

I'm a Python developer from Mumbai, mostly working with Django, PostgreSQL and AWS, and React on the frontend.

I've worked on ERP systems, multi-tenant platforms, real-time tracking and reporting APIs, where performance and data accuracy really matter. I enjoy making slow things fast and complex things reliable.

Lately I've been building my own products end to end. Still learning, still building.
