Project

RepoMind – AI Codebase Explorer

GenAI-powered tool for querying GitHub repositories in natural language. Built a 3-layer RAG pipeline with AST chunking, vector search (Upstash), and reverse-import lookup. Integrated Groq + Jina LLM APIs with a Redis token bucket capping calls at 25 RPM. Reduced ingestion time from ~90s to 2–3s by replacing git clone with parallel GitHub API fetches.
