About
Hi, I’m Zulfahmi.
I’m a senior software engineer in Sungai Udang, Melaka. I lead a Flutter team, and I like building software that holds up once people start relying on it.
I currently head a Flutter team of seven engineers. We’ve shipped 5+ production apps with 50k+ downloads, and we’ve had to move quickly without losing track of quality. Before that, I worked on .NET and web systems, including a government membership platform that reduced card issuance from days to seconds and a state border-management system delivered during COVID.
The projects here are the kind of problems I enjoy: payments, OCR, scheduling, rendering. They force you to be clear about rules, failure modes, and what AI should or should not decide.
Places I’ve worked
