I've built production backend and full-stack platforms at Tayog and GIAN, IIT Hyderabad, owning features from system design through deployment.

At Tayog, I delivered mentorship and payments workflows for a 5,000+ user research platform, including REST APIs, PostgreSQL schemas, Next.js interfaces, Razorpay flows, OAuth2 authentication, and Kafka-based researcher verification.

At GIAN, IIT Hyderabad, I owned course-management features for an ERP and CMS serving 10,000+ daily users during peak academic sessions. I reduced course-search latency from 165 ms to 24 ms through PostgreSQL indexing, optimized joins, conditional queries, and input debouncing.

I've also built high-throughput Java/Spring Boot services, AI-powered Gmail tooling, event-driven microservices, and a campus recruitment platform used by 1,200+ students and 200+ companies.
