For data scientists building apps

Ship the app, not the notebook.

Your model works in a notebook. Now build the application that puts it in front of users. Learn app architecture through interactive exercises.

Typed language with clean syntax and async/await. If you write Python with type hints, Dart reads naturally.

SOLID and DRY courses teach how to structure code that other people can maintain. The patterns your production app needs.

Flutter builds for iOS, Android, and web from one project. Your model gets a real frontend everywhere.

Dart + Flutter + SOLID + DRY

From notebook prototype to production app.
