I build practical decision tools that turn complex, real-world data into simple, usable products — with data, AI, and modern web technologies.
A common pattern runs through my best work — Data → Reasoning → Decision → Product: I take messy or hard-to-read information (live transit feeds, weather, hospital queues, market data, brewing parameters) and convert it into a tool that helps someone make a better decision in seconds.
Mostly Hong Kong–focused, mobile-first, and shipped as PWAs or web apps.

I work as an AI-assisted product builder — I define the problem, design the product, and direct AI coding agents to ship it.
