I have over 15 years building applications. Mostly on the web (Rails, Ember, node) and more recently mobile apps with Flutter.
I recently open sourced Flutter Data, the best library for managing persistent data in Flutter applications.
In 2015 I started a blog called Ember Igniter where I address tons of issues and questions Ember developers have. It's been a fun and rewarding endeavour. Now, I'm working on the Flutter Igniter blog!
I enjoy actual code challenges but, above all, knowing when that software makes someone's life a bit better.
Arc/Codementor is a great platform for me to help you out with the development of your apps. Let me know!
