What I'm looking for

I'm looking for high-ownership, fast-moving work where I can build AI/ML infrastructure, RAG systems, search, and distributed backend platforms end-to-end, from architecture and data pipelines to low-latency serving, CI/CD, and observability.

I've built search, ranking, and AI systems for JioSaavn, Collectcent, DocNexus, and NextDoorDukaan, including services supporting 160M+ active users. At JioSaavn, I productionized deep-learning search ranking and personalization systems that improved search relevance by 20% and accessibility by 45% for non-Latin-script queries.

At Collectcent, I built real-time ML ranking and bidding models that delivered a 25% ROAS improvement and $2M+ annual impact, while cutting model training time by 60%. At DocNexus, I architect RAG, entity-matching, analytics, and event-driven ML services for NexusIQ, including physician-publication matching across 100K+ documents at sub-second latency.

I've also co-founded and built a two-sided marketplace backend from zero to production, owning architecture, infrastructure, testing, and documentation end-to-end. I enjoy high-ownership work across Python, Go, cloud infrastructure, LLM tooling, data pipelines, and low-latency distributed systems.
