What I'm looking for

I'm looking to help companies build high-quality Flutter products, solve complex mobile challenges, and improve user experiences through maintainable architecture, reliable integrations, and collaborative delivery.

I've built Flutter applications for OmniShelf, HTSS clients, HYLL AG, and Smart Nedavi across retail, construction, pharmaceutical, travel, and energy products. At OmniShelf, I rewrote a Unity app in Flutter, doubled user satisfaction, and owned the app architecture.

I build maintainable cross-platform products using Flutter, Dart, BLoC, Clean Architecture, REST APIs, Firebase, and local storage. I've integrated C++ through Dart FFI, built custom Java camera plugins with Method Channels, and improved data reliability through local caching.

My work has increased user engagement by 22%, reduced app crashes by 55%, doubled retention, and cut installation time from 15 minutes to 3. I also lead developers through planning, code reviews, and architectural best practices while collaborating closely with design, backend, and testing teams.
