Training web accessibility

For the Dutch training institute The Internet Academy I teach about WCAG.

For The A11Y Collective I created 4 courses for The A11Y Collective: “Web accessibility, the basis“, “Writing accessible content for the web“, “Accessible code” and the masterclass “ARIA explained“.

For the Dutch organisation Thuiswinkel.org I participated in creating the e-learing programm Digitale Toegankelijkheid for webshop owners about what web accessibility is and how to start.

Open source contributions

In 2025 I started contributing to the WordPress accessibility documentation again. My goal is to expand and modernise the information available on accessibility for WordPress developers, designers and content creators. Follow my work on WordPress.org #wp-a11y-docs. Feel free to sponsor me.

Until October 2018 I was an active part of the WordPress Accessibility Team. For this I got props for several WordPress releases and “rockstar” credits for 4.3 & 4.5.

In 2016 Knowbility gave me the Heroes of Accessibility Award for Individual Achievement for my contributions to WordPress.
