Hello, I am Stefan.

I'm widely considered leading expert on software development.

I'm a software success consultant specializing in software architecture, design patterns, object orientation, as well as designing, building and maintaining complex systems.

I firmly believe that not technology, but humans should be put first.

I am an Open Source advocate. I helped found The PHP Foundation and I am the CEO and Co-Founder of The PHP Consulting Company (thePHP.cc). We offer consulting, coaching, and training.

I'm creating THE FLUENT DEVELOPER, a learning platform that makes you a super software developer by teaching everything I have learnt in 40 years.
