I'm building high-throughput distributed systems, vector search engines, and secure AI infrastructure.
IndiaWhat I'm looking for
At Zettascape, I architected a vector search engine with JVector and HNSW, reducing graph load time from 95 seconds to 67ms through on-disk persistence and lock-free graph node deletion. I've also built a SQL-only MCP server and AI-agent capabilities with tool calling, multi-turn sessions, and persistent memory.
Previously, I built payment infrastructure at Nimbbl handling 100K+ daily transactions, cut transaction response times from 1s to 50ms, and delivered card tokenization and real-time routing systems. Across Jarvis and Tata Consultancy Services, I've delivered Redis-based caching, microservices migrations, healthcare APIs, automated testing, and database optimizations for high-volume applications.
