About me

My name is Sebastian Bergmann, and I have been working as a software developer and consultant in the PHP ecosystem for over 25 years. I support development teams in creating better software through modern practices, tools and training.

I am deeply committed to Open Source, maintain critical Open Source projects in the PHP ecosystem, and help shape the work of the PHP Foundation as a member of its board. I have also represented the interests of Open Source at the European Commission and am active in the Open Source Working Group ("Arbeitskreis Open Source Software") of the German Informatics Society ("Gesellschaft für Informatik").

I live and breathe Open Source and help shape how developers around the world test, write, and maintain their code.
