About

I build production-ready Agentic AI systems conversational agents, RAG pipelines, and LLM-powered automation tools that solve real business problems. My core stack: Python · LangChain · LangGraph · CrewAI · FastAPI · Streamlit · DSA · HuggingFace. What I bring to a team: → End-to-end ML projects: from data ingestion to deployed API → Agentic workflows using multi-agent frameworks (LangGraph, CrewAI) → RAG systems with semantic search and vector databases (Pinecone) → Clean, documented, scalable code with a product-first mindset Currently completing my BCA at Maharshi Dayanand University (2025) and building in public — every project is live on my portfolio. Open to: AI/ML roles | LLM Engineering | NLP | Full-time or internship opportunities.
