I've led production-grade AI applications and enterprise software at Innovative Application Consultants India, including scalable FastAPI microservices supporting 600+ concurrent users with zero reported production issues. I also collaborated on enterprise AI solutions for Microsoft and Maruti Suzuki.

At Certa, I redesigned core product architecture around a Retrieval-Augmented Generation pipeline to improve response accuracy, scalability, and operational costs. I've also automated product analytics reporting through time-triggered AWS Lambda functions.

I build practical AI products across query management, lead management, analytics automation, and hiring workflows, combining RAG, backend optimization, distributed systems, and cloud infrastructure.
