I am part of the community that develops and maintains the open source Content Management System TYPO3. As a framework merger I contribute a lot of time for reviewing and testing patches. I maintain some extensions for TYPO3 as well.
Additionally I write blog articles about technical topics regarding TYPO3 CMS over at usetypo3.com where I also have a Patreon going. To offer flexibility to sponsors, I am now happy to be on GitHub Sponsors as well.
