Felix Arntz
Senior Software Engineer – Google LLC
Felix is a Senior Software Engineer at Google and a WordPress core committer from Germany, currently residing in San Francisco, California. He helped establish the WordPress Performance Team and is primarily contributing to its efforts at the moment.
Felix has been using WordPress for a decade and contributing back to the project since 2015, being credited as a contributor on every WordPress core release since 4.3. Over the years, he has been a maintainer of different components, such as Multisite, Capabilities, and REST API. Since November 2016 he has been a WordPress core committer. Most recently, he has stepped into the role of the inaugural Performance Lead for the WordPress 6.2 release. Throughout his time as a WordPress contributor, it has been a priority for him to help other contributors onboard and grow, which he has demonstrated through several efforts like driving documentation, leading WordPress core tables during WordCamp contributor days, as well as speaking about ways to contribute more efficiently.
Felix specializes in performance optimization in WordPress and is eager to identify opportunities for performance enhancements that work out of the box and can positively impact most WordPress sites around the globe. One of his key goals is to promote measuring performance when developing for WordPress, to gain a true understanding of how a certain change impacts performance and to discover performance regressions before they could make it into a release.
Before his current job at Google, Felix worked as a freelancer implementing WordPress solutions for various companies. As part of that, he worked with companies like Yoast, WP Engine, and Usability Dynamics, to name a few.
Outside of the web, he spends his time producing music, hiking, learning Spanish, and drinking Mountain Dew.
