About

A developer workspace with laptop, notebook, and warm desk lamp

I'm Toby. Developer, educator, and builder based in Hong Kong.

I teach people how to code with AI, and I use AI to build my own tools. This site is where I write about the process — the ideas, the experiments, and the things I learn along the way.

Everything here starts from first principles. I care about understanding how things work, not just making them work.

The best tools are built by people who need them.
