About lum1104

Builder working on LLM applications, memory systems, graph-based RAG, and multimodal AI.

MS ECE, Georgia Tech. Previously did algorithm engineering work at Tencent and Baidu.

I’m building Understand Anything, an open-source tool that turns any codebase into an interactive knowledge graph for exploration, search, and plain-English understanding.
