About me
Hi, I'm Fierlyan a Flutter and iOS developer based in Indonesia, currently studying Computer Engineering at PENS.
I focus on shipping working MVPs and fixing real bugs in existing apps, not just prototypes. Recent work includes JariLingo, a real-time on-device AI app (custom transformer model, 90%+ accuracy, runs fully offline on iPhone), and VillaVibe, a Flutter rental platform with full booking and account flow.
I only take on work that matches what I've actually built before, so what you see here is what I can reliably deliver, no surprises halfway through.

I've got a response within one hour even if it was the middle of the night in Indonesia. Delivery was also sooner than promised and good. Highly recommended.
