At Workato, I lead eight engineers building a multi-tenant enterprise search and AI platform on a 24-node OpenSearch cluster serving 220M+ documents. I designed hybrid BM25 and KNN retrieval with cross-encoder reranking, improving nDCG@10 by 32%.
I build grounded-generation systems end to end, from query classification and permission-aware retrieval to hierarchical chunking, context assembly, and citations. Fine-tuning embedding models with LoRA lifted Recall@K by 22% without increasing serving cost.
Previously, I led Dell's migration from Coveo to Elasticsearch, saving $2.7M in licensing costs while maintaining operational continuity, and shipped a multi-agent RAG system that cut agent turnaround time by 60%. As CTO and co-founder of mello.fun, I raised a $250K pre-seed round and led a 12-engineer team building semantic search for 50K+ active users.
Across Foundit, Zetwerk, Seven Lakes Technologies, and Innoplexus, I've delivered search systems that improved matching, relevance, latency, and infrastructure cost. I hold four granted patents in information retrieval and have spent a decade organizing the Elasticsearch and OpenSearch community in India.
