My name is Inayaili de León and I'm a Design Producer at GitHub — working on design systems, design operations, and more. I'm a published author and international speaker.

I'm Panamanian Portuguese, born in the USSR, and have lived in London (the best city in the world) since 2008.

I love naps, cats, and Earl Grey. And I'm obsessed with podcasts.
