A designer who likes making things work.
I’m Jaime Caballero, a design engineer based in London. I design systems, implement and extend existing ones, and build tools with AI. I like being close enough to the code to make the details work.
I’ve designed card experiences at Wise, commerce tools at Moteefe, booking experiences at eola, and moderation products at Checkstep. Since December 2023, I’ve also worked on freelance development for Glass Coffee, including its storefront and custom internal tools.
AI helps me build and iterate faster. The part I enjoy is turning its output into something people can understand, edit and use.
I have a BS in Computer Science, a longstanding love of typography, and a habit of opening the browser to work an idea through. Away from the screen: coffee, salsa and cooking for people.
Working together
I’m available 1–3 days a week for design systems, frontend implementation and AI-assisted product work. I can join an existing team or take a focused problem from design through implementation.
