Hi, I’m Lea! 👋🏼 I make things that help people make things. Ι design web technologies implemented in your browser, launch open source dev tools used by millions, and consult on my areas of expertise. I hold a PhD in usability & innovation from MIT — but chose product over research. I love sharing knowledge and speak, teach, write, and blog about product design, web technologies, usability, and their intersection.
