Onboarding new users

Improved Core Web Vitals on high-traffic hotel landing pages used by millions of users, reducing LCP from 3.4s to 1.2s and CLS from 0.200 to 0.001 by optimizing render-critical resources, layout stability, and asset loading strategy.  

Led end-to-end development of a real-time promotional platform, acquiring 25K+ users within 24 hours and generating IDR 50M+ in reward redemptions. 

Reduced page load time by 58% (1.9s to 0.8s) by redesigning frontend asset delivery with route-based code splitting, dependency pruning, and optimized bundle loading.  

Drove ~60% analytics cost reduction (~$250K/year) by consolidating the frontend analytics stack into Mixpanel, architecting a shared implementation across product verticals with a Singleton pattern and a feature flag constructor requiring minimal per-vertical changes, reducing shared library bundle size by ~50%. 

Increased unit test coverage from 0.67% to 42% by introducing testing standards, regression suites, and CI enforcement, significantly improving release reliability. 

Built in-app communication feature (~500 MAU) and rebuilt Help Center platform, improving organic search traffic by 50% via SSR, structured metadata, and performance optimization.
