Sebastian Bergmann's Open Source Work
Open Source is the foundation of modern software development, especially on the Internet.
I love, contribute to, and am committed to Open Source. I helped launch The PHP Foundation and represented Open Source interests at the European Union.
Since 2000, I lead the development of PHPUnit. Through my work on this industry standard, I contributed significantly to the professionalization of the PHP community.
You cannot buy PHPUnit, but you can pay for PHPUnit. And the best way to do so benefits you, your team, and me: let me help you through consulting, coaching, and training.
Of course, you can also sponsor my work on PHPUnit.
