99% Usahaku
Telkomsel
A marketplace app for MSME and Telkomsel products on Android/iOS. Building new features, API integrations, and performance improvements for a nationwide user base.
About the project
99% Usahaku is Telkomsel's marketplace app that brings products from small and medium businesses together with Telkomsel's digital products in a single platform. It is available on Android and iOS and built with React Native.
Development follows an agile process so new features ship regularly. I work across the full mobile development cycle — from building the UI for new features and integrating APIs to keeping the app stable and performant at nationwide scale.
My contribution
- Build user interfaces for new features and integrate them with backend APIs
- Resolve bugs reported from production
- Improve the app's security, performance, and code quality
- Review other developers' contributions before they are merged
- Keep up with evolving concepts and best practices in mobile development
