PERSONAL ENGINEERING LAB
About
A quiet place to document the work behind useful, understandable AI systems.
I’m an IT engineer working on artificial intelligence products at CITIC.
This site is my personal engineering notebook — a place to explore LLMs, agents, model routing, RAG, context engineering and AI product design through notes, experiments and open-source projects.
Everything published here reflects my personal research and opinions.
How I use this lab
Build small experiments before forming strong opinions.
Make routing and model behavior inspectable.
Document trade-offs, not just successful outcomes.
Keep personal research clearly separate from company work.
