What I'm looking for

I’m looking for a role where I can own end-to-end production systems—backend APIs, real-time async workflows, and mobile delivery. I thrive in teams that value performance (latency down to hundreds of ms), clean architecture, and autonomous CI/CD.

I’m a Full Stack Engineer with 4+ years of end-to-end experience building and operating production systems at scale. I’m currently the sole engineer behind an enterprise ERP platform serving 14,000+ daily active users—owning API architecture, database design, server infrastructure, and CI/CD pipelines end-to-end.

I specialize in Django REST Framework, Celery, Redis, and WebSockets for backend performance and real-time experiences, plus Flutter, Firebase, and Android for mobile products. I’ve delivered 100× API performance improvements (21 seconds → 200ms), built bulk async notification pipelines reaching lakhs of users, and managed multi-tenant ERP architecture, MSSQL stored procedures, and autonomous deployments.
