Hello, I am Stefan.

I'm widely considered leading expert on software development with PHP and related technologies. I specialize in software architecture, design patterns, object orientation, and humans.

I love Open Source. I helped found The PHP Foundation and co-founded The PHP Consulting Company (thePHP.cc). Through this company, I offer consulting, coaching, and training.

I'm creating THE FLUENT DEVELOPER, a learning platform that makes you a super software developer.
