TOBING
I build production-grade Android apps for tens of thousands of users. 7+ years of Kotlin, architecture, and shipping things that actually work.
About Me
I started building Android apps in Jakarta in 2016 and spent 7+ years shipping production apps used by tens of thousands of people across fintech, education, and enterprise.
In 2024 I made the move to Brisbane, Australia to pursue a Master of Information Technology at Griffith University — expanding my expertise into backend systems, secure API development, and full-stack engineering.
I care deeply about clean architecture, performance, and building things that actually work at scale.
