About

I’m a Software Engineer III at Zinnia, where I build the distributed systems powering the PolicyGenius Marketplace. I specialize in making high-throughput services faster and more reliable. Recently, I engineered an orchestration engine that slashed workflow latency by 95% (from 20s down to < 1s). Before this, I was at Delhivery managing event driven systems that handled over 2 billion updates daily. I also build production grade AI that solves actual business bottlenecks. I’ve architected Agentic RAG engines that cut insurance issuance times by 72% and maintain Resume Matcher, an open-source project with 26k+ stars on GitHub. Currently, I’m wrapping up my M.Tech in AI & ML at BITS Pilani.
