Learning by Building

Notes on software, systems, and building things.

A personal tech blog. I write about what I'm learning, building, and thinking about — software engineering, systems design, developer tools, AI, and whatever else catches my attention.

Projects

Building with the garage door open:

• Metis — A knowledge engine that transforms books and articles into structured, retrievable expert knowledge for LLMs.
• Flair v1 — A voice-first AI campaign studio, built on Gemini Live API with real-time image generation.
• Flair v2 — A multi-stage AI pipeline that turns a brand brief into ready-to-publish social media campaigns.
• Parent Guidebook — A bilingual (EN/ZH) resource helping parents prepare for every aspect of raising their children.
