AI/ML engineer at NIT Durgapur building evidence-grounded LLM evaluation and agent systems.

India

Message

At NIT Durgapur, I research a deterministic analysis layer that grounds LLM answers in explicit evidence. I also wrote Python evaluation harnesses to benchmark retrieval quality, embedding performance, and answer correctness on enterprise datasets.

I designed and built Styme (StudyBuddy.ai), a LangGraph tutoring platform used by 100+ students, and maintain open-source agent governance projects. At FlyRank AI, I built and deployed LLM agents and tuned RAG pipelines; I also built projects including a Telegram financial assistant and a real-time deepfake detector.
