About

Base: Hyderabad, India
Experience: 5+ Years Active

I am a Full Stack Engineer based in Hyderabad, India. My work bridges the gap between nuanced product interfaces and resilient backend engineering.

Full stack engineer with 5+ years designing and shipping production web and mobile systems on Node.js, NestJS, React, Angular, and React Native. Experienced owning features end-to-end — from data modelling and API contracts through deployment, real-time WebSockets, and production monitoring.

I prioritize clean mental models, deterministic data flows, and low-latency systems. I believe codebases should be as readable and maintainable for engineering teams as the interfaces are intuitive for customers.
