I build AI-powered RAG applications and full-stack APIs with Python and React.
IndiaWhat I'm looking for
I've built AI-first applications including an HCP CRM interaction module, where a LangGraph agent uses natural language to autonomously complete live forms through multi-step tool execution.
I developed a RAG assistant for industrial electrical fault diagnosis using LangChain, FastAPI, ReactJS, Qdrant, MongoDB, and OpenAI/Gemini. It processes technical manuals, retrieves relevant documentation, and delivers source-grounded troubleshooting responses.
Before moving into AI and full-stack development, I worked as a Junior Engineer in electrical maintenance at Maithon Alloys Ltd, diagnosing critical equipment faults and coordinating maintenance across shifts. I'm eager to apply my Python, FastAPI, ReactJS, and LLM skills to build innovative AI-driven solutions.
