What I'm looking for

I'm open to impactful Android or cross-platform opportunities where I can build scalable, stable systems, contribute to real-time and high-engagement products, and grow as a system-level engineer.

I've built high-engagement Android experiences at Creative Frenzy and Eloelo, including live streaming, virtual gifting, community features, games, and onboarding flows.

At Creative Frenzy, I led Zeeplive's Party Streaming migration from ZEGO to LiveKit, implemented MediaSoup with WebRTC and WebSocket communication, and resolved more than 32 legacy crashes. I also built dynamic payment flows, real-time Astro Bot communication, and an AI-powered Party theme generator.

I work in Kotlin, Jetpack Compose, Clean Architecture, and MVVM, with a stability-first approach to modular systems, ANRs, memory leaks, and legacy migrations. I'm also exploring Kotlin Multiplatform to share business logic across platforms and build products that scale.
