I'm a software developer based in Kolkata, India, currently working at Tata Consultancy Services (TCS). I specialize in designing and scaling production-grade RAG pipelines, GraphRAG systems with Neo4j, and high-throughput FastAPI LLM microservices.
My goal is to engineer reliable, deterministic intelligence layers on top of modern language models. I'm actively moving toward GenAI Engineer / Forward Deployed Engineer roles at AI-first product companies.
