Welcome
Hi, I'm Gang — an entrepreneur and a developer. I've been building my own things since 2020. ApiCat was the first, SupSub is what I'm working on now, and I haven't stopped since. Whether it's starting companies or writing code, it really comes down to this: I love making things. Turning an idea into something real is the most reliable way I know to feel a sense of accomplishment. Reading, writing, thinking, and coding take up most of my days — they're also how I make sense of the world. On this blog I write about all kinds of things: thoughts on building products, notes on life, technical write-ups, what I'm learning, good food I've had, films I've enjoyed. No fixed topics — just whatever's on my mind.
