Full Stack Engineer @ Talview | Node.js · TypeScript · NestJS · PostgreSQL · GraphQL · AWS | Building scalable proctoring infrastructure

About

I build backend systems that power real-time exam proctoring for enterprise clients at Talview — a platform trusted across education and hiring. Day to day, I design and ship features across a stack that includes Node.js, TypeScript, NestJS, PostgreSQL, GraphQL (Hasura), Docker, Kubernetes, and AWS. Recent work includes architecting a session replay storage pipeline (rrweb events compressed to S3, metadata in PostgreSQL), building database migrations across multi-tenant schemas, and integrating FingerprintJS Pro via CloudFront proxy for device identification. What drives me: solving real infrastructure problems — data modeling trade-offs, migration ordering bugs, GraphQL query correctness, webhook debugging — not just writing CRUD endpoints. Currently exploring opportunities as a Backend Engineer at product companies in Bangalore. If you're building something interesting, let's talk → gagan8055r@gmail.com or "DM me".
