I build production-ready web applications, AI-powered systems, and agentic workflows, from requirement analysis through cloud deployment.

At QuadNite Systems, I architected React.js, Node.js, and MongoDB applications with JWT authentication, admin tooling, third-party API integrations, and payment flows. I deployed frontend services on Vercel and backends on AWS, contributing to a 30% improvement in user experience through asynchronous and real-time data handling.

At HdMediaNetworks, I engineered Python and Django backend services, documented REST APIs, and optimized MySQL schemas, indexes, and query logic to improve high-traffic API response times by 20–30%.

I also build grounded AI products such as Tender Intelligence Agent, MongoSense, AI Blog Writing Agent, and Self-RAG. My work spans FastAPI, LangChain, LangGraph, RAG, PostgreSQL/pgvector, MongoDB, Docker, and evaluation-focused workflows with citations, guardrails, and automated testing.
