What I'm looking for

I'm looking to build high-impact mobile products, lead clean architecture and delivery practices, and help teams create reliable Android and Flutter experiences at scale.

I've shipped mobile improvements for 300M+ monthly active users at PayPal and helped raise Foxbit's app store rating from 2.8 to 4.4 stars. I build Android and Flutter products with a focus on stability, onboarding, architecture, and user experience.

At Universal Leaf, I'm launching a new Agro app with negotiation and visit features while introducing clean architecture, BLoC/Cubit, PR rules, and Azure DevOps CI integration. Previously, I led Foxbit's migration from native Android to Flutter and built its global crypto trading app from scratch.

I'm also the founder and instructor of Lovepeople, where I built a school and trained 200+ Flutter engineers. Across fintech, streaming, crypto, and startup teams, I've worked with Kotlin, Dart, Clean Architecture, CI/CD, and mobile platform integrations.
