At Zytronic, I engineered a live-streaming module with 1vs1 and 2vs2 PK battles, using ZegoExpressEngine and ZegoEffectsPlugin. I also developed WebSocket features for instant messaging, live comments, and stream updates.

I led the application's migration from BLoC to Riverpod and architected a Cache-First data layer with Hive for the Vibes short-form video feed. I also implemented social features, virtual gifting, and in-app purchases.

Previously, at Super App, I engineered and deployed cross-platform applications published on the Apple App Store and Google Play Store. I used Riverpod and Clean Architecture, integrated Firebase, Supabase, and REST APIs, and conducted manual and widget testing.
