About

Efthymios Sarmpanis

Hi, I'm Efthymios Sarmpanis, a software developer and community organizer based in Greece.

I specialize in Flutter and Dart development, with a focus on clean architecture, feature isolation, and testing best practices. I'm passionate about building maintainable mobile applications and sharing knowledge with the developer community.

Community

In 2019, I founded the Flutter Greek Community and the Flutter Athens Meetup to bring together developers interested in mobile development with Flutter.

From 2020 to 2025, I was recognized as a Google Developer Expert in Dart & Flutter, during which I delivered conference talks on Flutter, testing, and feature isolation.
