I build high-scale Golang backend platforms, distributed systems, and AI-enabled enterprise services.

Message

I'm building and converging transactional systems of record at Intuit, aligning data contracts across 20+ downstream microservices while maintaining continuity through backward-compatible API changes.

At AiDash, I owned the backend architecture for the Hazard Tree Management module and redesigned data access and caching to reduce critical query latency from several minutes to under five seconds. I also built a secure internal RAG-based AI assistant using LangChain, PGVector, and Ollama for offline enterprise inference.

Previously at Swiggy, I built a gRPC-based API lifecycle platform and configuration systems for distributed services, helping reduce integration issues by 30% and deployment failures by 40%. I scaled backend systems to handle 2,800+ QPS during peak food-delivery demand.

I've also delivered cashierless retail backend services at Tesco, IAM and audit systems for regulated financial clients, and scalable Java APIs across e-commerce, workplace management, healthcare, and enterprise domains.
