Real-World Books

The Real-World Dev Blog

Empowering the next generation of developers

Welcome to Our Blog!

You learned the theory. You aced the exams. You’ve built perfectly controlled, simple applications in school.

But let’s be real: none of that is going to help you at 4:59pm on a Friday when the deployment fails.

Being a developer in the real-world is a different game. The Real-World Dev Blog is where you learn how to play.

Real-World Dev Style.
