What I'm looking for

I’m looking for a team where I can own API-first backend systems and microservices with React delivery—focused on performance, real-time features, and clean engineering practices, with room to grow architecture and mentor others.

I’m a Senior Software Engineer with 4+ years building and scaling backend systems for enterprise leasing and finance software. I specialize in designing REST APIs and microservices in Python (FastAPI) backed by PostgreSQL, with full-stack ownership through React.js delivery.

At NETSOL Technologies, I progressed from Associate to Senior while taking on architecture, real-time features, and technical mentorship. I delivered measurable impact—cutting API response times by up to 50%, automating data pipelines to remove 40% of manual effort, and shipping large refactors with zero regressions.

I lead API-first development using Pydantic-validated request/response handling, OAuth2/JWT security, and SSE-based real-time updates. I also emphasize performance, observability with CloudWatch, and reliable releases through pytest, Jest, and strong code review practices.
