Speed is a byproduct of trust

LLM-based tools make it easy to go fast, and just as easy to go fast in the wrong direction. Teams do not move faster despite their quality controls. They move faster because they can trust them.

About me

I am Sebastian Bergmann. I started writing PHPUnit in 2000 and still maintain it. In the same year I gave my first talk at a PHP conference. As a co-founder of thePHP.cc, I help teams in training courses and through consulting and coaching with everything related to PHPUnit, with quality gates for working with LLM-based coding agents, and with supply chain security.

I helped start the PHP Foundation and serve on its board. I have also represented the interests of Open Source at the European Commission and am active in the Open Source working group of the German Informatics Society (Gesellschaft für Informatik).

Where you can meet me next is listed under events. The next dates of my training courses are in the training overview.

Let's work together

Do you want your team to get better at testing? I can help with consulting, coaching, and training.
