Joel Califa is a design leader with 15 years of experience building product-facing interfaces and design systems, currently serving as VP Design at Unify after leadership roles at Heap and GitHub. He led design for GitHub Pull Requests and contributed front-end refinements to GitHub’s widely used Primer CSS, showing a blend of product thinking and hands-on UI engineering. Joel’s background spans startups and scale-ups—from running product design at DigitalOcean to teaching front-end development—so he pairs strategic vision with practical implementation. Based in New York, he brings a pragmatic focus on components and workflows that help people “make things,” and his history as both designer and developer means he often ships the detailed work others delegate.
