For startups rebuilding on Flutter
Rebuild faster. Rebuild right.
The old stack isn't working. You need cross-platform, you need speed, and you need architecture that won't trap you again. Learn Flutter the right way.
Get productive in days
You already know how to code. The Dart course gets experienced developers fluent fast. Skip what you know, focus on what's different.
Don't repeat old mistakes
SOLID and DRY courses ensure your new codebase starts with the architecture your old one lacked.
One codebase this time
Flutter gives you iOS, Android, and web without maintaining separate codebases. That's the whole point of the pivot.
Dart + Flutter + SOLID + DRY
New stack, better foundations.
