Tech Lead at Fireflies.ai, building agentic AI systems and LLM architecture for meeting intelligence at scale.
15+ years in software engineering, with a physics background (BS + MS). I've worked across AI, medical imaging, astronomy (CARTA, an international C++/JS open-source project at Academia Sinica), IoT, and streaming — primarily in TypeScript, Python, and C/C++.
Beyond code, I've built and led mobile and full-stack engineering teams and introduced Agile practices across organizations.
Currently into: LLM agent architecture, RAG systems, context engineering, MCP tooling · Contributor to the MCP TypeScript SDK
