FULL
STACK
Full Stack Developer in Jakarta building seamless, user-friendly web, Android, and game experiences that feel alive.
ABOUT
I'm a full-stack developer who loves turning ideas into things people actually enjoy using. My work spans full-stack web, Android, and game development, but the throughline never changes: building seamless, user-friendly applications and digital experiences that feel alive. I care deeply about clean code, sharp UX, and shipping work that holds up in the real world.
Outside of pure engineering, I'm a maker at heart — I edit, shoot photography, and produce videography, so the visuals always match the products I build. That blend earned 2nd place in the Politeknik Tempo University English Speech Contest (2023) and 3rd place in the FLS2N Short Movie Contest.
