Dexter Leng

I’m a incoming Year 3 Computer Science student @ National University of Singapore. I enjoy Mac development and reverse engineering. I’ve created several revenue generating Mac apps while I was in high school & army. One of my projects - Homerow was acquired in 2024 for five-figures. I’ve worked on popular Mac apps like MacGPT as a freelancer.

I’m currently working on ProNotes. It’s a macOS extension for Apple Notes that adds markdown, slash commands, AI, and other good stuff. Exploring compilers, kernel dev, and whatever peaks my interests really.

Over the years I discovered I love building things that shouldn’t be possible - at least not at first glance. It’s why I made the apps I made.
