What I'm looking for

I want to build production-grade LLM backends—RAG, agentic systems, and distributed async pipelines—where I can strengthen AI infrastructure and developer tools with reliable engineering and scalable architecture.

I’m an AI Backend Engineer focused on production-grade LLM applications, RAG pipelines, and distributed backend systems. At Tata Consultancy Services, I designed and shipped 15+ backend services across enterprise automotive workflows, owning the full lifecycle from design to deployment.

I built reusable backend architecture with Express middleware for request validation, exception handling, and response contracts, reducing feature delivery and bug turnaround time by 25%. I also led production incident resolution across distributed services with zero-regression hotfix deployments.
