Hi, I’m Lea! 👋🏼 I make things for making things. I’m an award-winning web standards leader, and have designed several web technologies implemented in your browser. I have launched 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.
