Work Experience

PT Jalan Terus Saja (ReCharge)

https://www.recharge.id

Android Developer

ReCharge is a mobile app that allows users to rent powerbanks from smart stations across Indonesia. It's my first job as an Android Developer where I'm exposed to agile software development with very lean product engineering team (less than 10).

During my first several months, I'm handling the development of the mobile app (which still native & lot's of Java code back then) with the guidance of the Senior Developer. Then I move into handling the powerbank smart stations which uses an Android TV board. I learnt a lot about Firebase, and problem solving as we had to occasionally do troubleshooting with our overseas partner.

Software Engineer - Android

Mapan is a social enterprise that helps low-income women in Indonesia achieve financial independence through arisan and reseller businesses. I'm responsible for developing features and maintaining the Mapan Android app. The app does a lot of AB testing which heavily relied on Firebase Remote Config & Analytics.

Our team really adhere to SOLID Principles, the codebase has multi-module app architecture with MVVM and repository pattern, use Trunk based development, Dagger2 for DI and coroutines flow for reactive programming.

Here I learnt a lot about custom view and code reusability, writing technical documentation, and third-party services integration (i.e. AppsFlyer, Netcore). I also had the chance to reduce CI/CD build time by optimizing the linter process.
