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.
More recently, I was the first Performance Lead as part of the WordPress 6.2 release squad, the Co-Performance Lead for the WordPress 6.3 release, and later the Performance Lead for the WordPress 6.8 release. I’m currently mostly involved in the new WordPress AI Team, of which I am a founding member and initial co-Team Rep.
Over the course of time I have worked on tons of tickets and made 301 commits. Working on WordPress Core and other open-source projects is a high priority for me, so I ensure I have sponsored or personal time available to dedicate to it.
Software Engineer at Google
I am currently a Senior Software Engineer at Google, working on AI evals for web application code generation and assistance. The primary objective is to measure an LLM’s ability to generate or iterate on entire full-stack web applications based on natural language prompts, covering a variety of web abstractions and primitives.
In my previous role at Google, I was working on a team where we collaborate with and contribute to CMS platforms like WordPress to help web publishers and content creators succeed on the open web by enhancing user experience and performance out of the box. As part of this role, I co-founded the WordPress Core Performance Team.
Last but not least, in my first few years at Google I was the lead engineer for the Site Kit plugin for WordPress, designing the architecture of the plugin and building it from zero to launch to over 3 million monthly active users.
