I'm a senior software engineer focused on applied AI engineering — LLM/RAG pipelines, agent orchestration (LangChain, LangGraph), and voice agents wired into real applications. A recent project is the LLM/RAG pipeline for RCA Archive Research, a LangGraph agent that grounds answers in digitized source documents. Outside of tech, I run marathons (18 total, including all six majors), play piano, and enjoy hands-on projects — plus I do heritage research connected to Amoy (Xiamen) and RCA history.

Looking ahead

Build new, renovate the rest

Two lanes matter, and both are big: shipping new AI products, and helping companies modernize the applications they already run on. The second is less discussed and just as consequential — cloud migration and AI pipelines, woven in together, so existing software keeps pace with what's possible.

Focus areas

Practical building — real workflows, real constraints

Applied AI + software systems

I'm most interested in AI when it's wired into real products: LLM/RAG pipelines with source-grounded answers, agent orchestration that's observable, and systems that stay reliable under real usage.

  • LLM/RAG pipelines (LangGraph agents, retrieval, source-grounded answers)
  • Voice agent workflows (webhooks, recap/extraction)
  • Engineering habits: correctness, logs, retries, edge cases
