At PT Bank Rakyat Indonesia (Persero) Tbk, I contributed to the production release of MyBills, a scheduled bill payment feature. I implemented parts of the bill scheduling flow, including UI screens, input validation, and business logic, and contributed to Gold Installment Schedule and Donation Schedule integrations.
At PT. Rakhasa Artha Wisesa, I developed and maintained Android applications and contributed to modular architecture and JNI/JNA integrations. I also introduced Jetpack Compose for new features and built EnumStore, an open-source Kotlin library for enum-backed key-value storage on Android.
