Sole Developer (Design, Architecture, Implementation)

Designed and built a complete AI codebase analysis platform on top of the open-source LightRAG RAG engine (MIT). My contribution: a Go-based CLI and a native C# analyzer that index code instantly and deterministically without an AI model; a git-aware file watcher that updates only changed entities; a security layer that redacts API keys and credentials before they enter the knowledge graph; an MCP bridge giving AI coding assistants structured access to the codebase; Docker-based orchestration with one-command setup; and integration of an interactive web UI for visual graph exploration. 226 automated tests, MIT-licensed.

I'm interested in long-term engagements where I take responsibility from day one: joining existing teams, improving architecture, and delivering features end-to-end. Currently I'm increasingly integrating LLM/RAG functionality into products (local LLMs, MCP, AI-assisted development).
