Senior iOS Engineer at ByteDance, maintaining Tokopedia’s recommendation feed and improving search results features.

At ByteDance, I joined the team integrating its analytics and event-tracking framework into the Tokopedia iOS app. I built and maintained reusable UI components for the homepage’s infinite-scroll recommendation feed, including real-time recommendation and flash-sale widgets.

I own ongoing feature development and production stability for the homepage and recommendation feed, addressing crashes and scrolling issues while delivering new features. Since early 2026, I’ve also contributed to search results growth initiatives, including product-card layout improvements, voucher and bonus widgets, and search event tracking.

Before the integration, I led Tokopedia’s iOS Communication team and refactored the chat room architecture from MVVM to The Composable Architecture. Earlier, I rewrote the buyer-seller messaging platform from React Native to native Swift and owned messaging and notifications; at Bhinneka.com, I developed iOS apps and C2C and B2B web applications.
