TL;DR about me
I’m a design engineer and product manager at Vimocity, a workplace health and safety platform based in Seattle. I lead design there. I built our design system — VimUI — and I maintain the standards and automated checks that keep our design and code in sync.
Nine years in design, five writing production frontend.
