Who I am
About
I learn by building new things.
I’m Eric Cheng — a developer in Hong Kong. By day I work in enterprise IT; by night I build the apps you’ll find on this site.
Every one of them started the same way: my family or I ran into a problem, went looking for an app, and found nothing that solved it properly. So I built it myself. Each app is designed, built and supported by one person — which means when you report a problem, the person reading it is the person who can fix it.
AI No Filler is where I record my study of AI — what I’m learning, what I build with it, and what actually holds up in practice.
