Hi, I'm Navneet Singh Arora!
I'm the first AI hire at Repath, where I built our agentic platform from 0→1 — a production multi-agent system on LangGraph and LangChain, evaluated with RAGAS and DeepEval. I designed the MCP integration layer with FastMCP and the API layer with FastAPI, managing ~100TB of climate and geospatial data end-to-end. Based in Hamburg, I care about systems that hold up in production, not just in a demo.
