Many of my products started with something I found clumsy to use, so I rebuilt the interaction myself. Tasks in my notes were too scattered and had no good view, so I made Task Genius to put them on boards and calendars; Markdown couldn’t be marked up like paper, so I made Su, which lets you handwrite right on the text.
From interaction design, frontend and backend to payments, licensing and long-term upkeep after launch, I can run the whole chain on my own. So far that is 18 products, about 1.3 million downloads, and about 50,000 active users outside the games.
Slow, memory-hungry software bothers me, and when something lags I want to dig down and fix it. I use Rust to cut agents’ memory use and response time, and go further down to local model inference, so the MOSS image model, too slow to use on a Mac, can generate quickly.
As long as I’m building something, it doesn’t matter whether it is productivity software, developer tools or game mods. Once it’s done I like to share it: I film the Slay the Spire 2 “monster duel” mod I wrote and post it on Bilibili, to give more players a richer way to play.
