 We started working with [David Luhr](https://twitter.com/david_luhr) last summer on a project-by-project basis to help us develop a Figma version of [Tailwind UI](https://tailwindui.com) _(almost ready!)_, as well as to leverage his accessibility expertise when building Tailwind UI templates, ensuring we were following best practices and delivering markup that would work for everyone, no matter what tools they use to browse the web.

 Coming up with an implementation for this was hard because it needed to be implemented with a box shadow, and we had to somehow make it composable with the existing box shadow API. There were many moments where I got frustrated and I might have even given up on it if I was working on it alone, but ultimately we figured it out and now it's one of my favorite features in the framework.
 
 David will be leading component and design asset development on Tailwind UI, and providing accessibility guidance on our other projects like Tailwind CSS and Headless UI. It's been an amazing experience working with him over the last 6 months and we are so excited to have him on the team full-time.
