What I'm looking for

I want to lead and build Flutter products with strong architecture, reliable API integration, and disciplined AI-assisted development. I’m looking for teams where I can mentor others, improve delivery speed responsibly, and ship real customer impact.

I’m a Flutter developer and team lead who builds and modernizes cross-platform mobile apps end-to-end—from architecture to debugging and production troubleshooting. I’ve been hired specifically for Flutter expertise, and I consistently take on more responsibility than the initial role.

At NetForemost, I started as an individual Flutter developer on an internal enterprise app and grew into leading multiple development teams. I coordinated legacy dependency/framework migrations across corporate Flutter apps, mentored junior developers, and structured backend systems and APIs in .NET consumed by Flutter and Angular front ends.

I also bring complementary backend and web experience, including REST API integration with Flutter apps and dashboards I built using Node.js and Angular. With Sof.ia, I redesigned modular architecture and routing, achieving 40% faster updates, then upgraded critical dependencies across Flutter, Gradle, and Kotlin.

I develop with AI tools intentionally—using GitHub Copilot, Cursor, and Claude Code with self-authored prompts to move faster while keeping code aligned with architecture and best practices. From integrating third-party SDKs (like MRZ document validation) to shipping production-ready solutions, I focus on quality, maintainability, and team impact.
