## About

```text
At PT Tokopedia, I was the tech owner and main contributor for Home, Browse Experience, and Recommendation, building modular widgets for acquisition through incentives and personalization.

I developed and maintained a shared recommendation widget for personalized content and page-level customization. I also made the app’s main navigation remotely configurable, with in-session updates and dynamic tooltips.

I collaborated with cross-functional teams to launch Tokopedia Now’s 30-minute grocery delivery feature, developing entry points with real-time cart logic. I wrote unit tests for implemented features and contributed to refactoring the app’s design pattern from MVVM to TCA.

At Bytedance, I contributed analytics integration into Tokopedia and upgraded server-driven navigation to real-time updates. I also integrated a gamification feature on the Home page and improved the Standalone Product Detail Page by moving widget control to the backend and adding interaction tracking.
