Work Experience
Enterprise Defense AI & Agentic Systems
Agentic AI Intern
Completed InternshipBharat Electronics Limited (BEL) — Central Research Laboratory - BEL
- ›Built enterprise Retrieval-Augmented Generation (RAG) microservice querying defense records, indexing 25,000+ docs in ChromaDB & FAISS.
- ›Engineered ingestion pipeline (parsing → chunking → embedding), cutting manual lookup time by 85%.
- ›Designed multi-agent reasoning workflows using LangGraph & LangChain for automated retrieval, boosting precision by 34%.
- ›Implemented hybrid search, cross-encoder reranking, and RBAC, achieving 92% top-k accuracy with zero data leakage.
- ›Shipped containerized LLM deployment using Docker & FastAPI, monitored with structured telemetry.
- ›Integrated modular AI agents, retrieval tools, and model-serving components into production-oriented workflows, enabling scalable and independently executable AI tasks.
