WordPress core contributions

I have been a WordPress Core Contributor since version 4.3 which was released in August 2015. I’m currently a component maintainer of the Multisite component and the REST API component, but regularly work in other areas as well. With WordPress version 4.6 I was recognized as a noteworthy contributor for the first time, and since November 2016 I have been a Core Committer.

Most recently, I was the first Performance Lead as part of the WordPress 6.2 release squad and the Co-Performance Lead for the WordPress 6.3 release.

Over the course of time I have opened 250 tickets, received 377 props and made 283 commits. Working on WordPress Core and other open-source projects is a high priority for me, so I ensure I have work time available to dedicate to it.
