Founder
I'm 17, a student founder studying Electrical Engineering and Computer Science at Diablo Valley College in Pleasant Hill, California. I build Unvibe because I kept shipping code AI wrote for me that I couldn't explain. Unvibe fixes that: select the code, press one key, and actually understand it.
I grew up in Jakarta, moved to Perth in 2021, and to California in 2025. I speak English, Indonesian and Mandarin.
I taught myself from Berkeley's CS285 and Stanford's CS234 lectures, on a MacBook with no GPU and no cloud budget. That constraint shapes how I build: things that work for people without the resources most tools assume.
I'm aiming to transfer to UC Berkeley, and I hold a 4.0 GPA while building Unvibe.
AI writes code faster than anyone can understand it. Students copy it, builders merge it, and nobody owns it. I wanted a tool that sits beside the editor, explains the exact code in front of you at your level, checks you got it, and keeps the lesson.
