What I'm looking for

I’m open to remote roles where I can own end-to-end systems—building scalable event-driven backends and React frontends, shipping LLM features to production, and collaborating closely with ML/data/business teams.

I’m a full-stack engineer with 5+ years building scalable, event-driven backend systems and clean React frontends using Java 17, Spring Boot, Kafka, Python/FastAPI, and AWS. At Paytm, I’m the sole owner behind a high-throughput SMS Parser platform (200M+ messages/day), scaling throughput from 30 TPS to 8,000 TPS by decomposing a monolith into 10+ microservices and unlocking ₹1,000Cr+ GMV.

I own projects end-to-end—from distributed system design for scale to shipping LLM features to production—partnering closely with ML, data, and business teams. I built MetaQL, a Looker-style internal analytics query platform with optimized Trino SQL, multi-tenant RBAC, and an AI-assisted LookML workflow, and I architected Zuno’s end-to-end GenAI SMS analytics pipeline that cut user-segment generation from 7–10 days to under 60 minutes.
