What I'm looking for

I’m looking to build scalable MERN systems with real-time performance and clean REST/GraphQL APIs, while applying AI (LangChain, RAG) to ship intelligent, production-ready features in a collaborative Agile team.

I’m a full stack developer with 5 years of experience building scalable web applications using the MERN stack. I focus on RESTful/GraphQL APIs, third-party integrations, and automated deployments with Docker & AWS, delivering performance and reliability through Agile/Scrum.

Recently, I built an AIRAG-based procurement chatbot and engineered real-time trading features with sub-50 ms order execution and WebSocket feeds supporting 100K+ concurrent users. I also developed RAG pipelines using LangChain, GPT-4 Turbo, Pinecone, and PostgreSQL, and I’ve improved user experiences with work like boosting Core Web Vitals by 30%.
