At Hyundai AutoEver Indonesia, I upgraded React Native to its latest version and migrated navigation to a native stack to improve maintainability and responsiveness.
I also implemented RTK Query stale-while-revalidate caching to reduce redundant API calls, and improved notification delivery by batching FCM token requests.
At Ruangguru, I developed and maintained web, mobile, and CMS applications. I designed a database-backed dynamic theming system for white-label customization and standardized CodePush versioning across apps.
At RubyH, I built a real-time waiting list system using WebSockets for banking clients and developed a full-stack HR system with Ruby on Rails integrated with Odoo.
