Hi, I'm Abhijeet
Backend & GenAI Engineer • Computer Science @ IIIT Vadodara
I build backend systems and AI-powered applications with a focus on FastAPI, Django, MongoDB and Retrieval-Augmented Generation (RAG) using LangChain and LangGraph. Currently working on Lumin, a modular chat platform that routes requests across different tools and models through a clean API layer.
