What I'm looking for

I’m looking for a remote-first team where I can ship production Flutter apps end to end, collaborate with global clients, and build high-quality native integrations and custom plugins using clean architecture.

I’m a Flutter Engineer with 4+ years of experience delivering production-grade Flutter apps across Android, iOS, and Web for international clients. I work end to end—from translating requirements into shipped features—while building custom native plugins when platform-specific capability is required.

My native background in Kotlin and Swift helps me bridge Flutter via Method Channels and Event Channels, including iOS CallKit-based integrations. I’ve also built and maintained production integrations for payments and releases, partnering closely with Product Owners, QA, and Backend Engineers in fast-moving, remote-first environments.

Across projects, I’ve refactored legacy code to improve stability and performance (including reducing app bundle size by 30% and resolving ANR-class crashes), and shipped apps that reached scale—such as 100,000+ downloads and 100,000+ installs—while maintaining strong app quality and user experience.
