About Me

I am a Full Stack & Generative AI Engineer specializing in the MERN stack, Next.js, and advanced LLM architectures. I bridge the gap between robust web development and state-of-the-art artificial intelligence by building production-ready AI applications, agentic workflows, and high-performance Retrieval-Augmented Generation (RAG) pipelines.

With hands-on experience integrating LLM APIs (OpenAI, Gemini, Anthropic), developing orchestrations with LangChain and LangGraph, and optimizing search indexes across vector databases (Pinecone, ChromaDB, LanceDB, FAISS), I design end-to-end intelligent systems. I combine full-stack engineering practices with MLOps awareness and containerized deployments to deliver scalable, secure, and recruiter-friendly solutions.
