Shater Tsavsar, product designer

I’m Shater, a product designer leading design at CostGraph.ai. I set the direction and look after the design system, all the way down to the React it ships as.

I call myself a Systemic Native: everything I do is grounded in some sort of system. I designed and built KernUI, a design system 1,200+ people use, and Luotain on top of its tokens, then pulled Luotain’s inputs out into Yöte, a React library you can just npm install.

CostGraph.ai Design direction, the design system and the product UI, built from zero with the team. Luotain Designed, built and shipped solo. A link and its QR code are one object, with their own scan data. Yöte Open-source React inputs. Zero dependencies, 24KB, one set of props across nine fields. Lönar Co-founder. Shipped the free invoice generator first, then built the platform on its feedback. KernUI 3,000+ components and 1,600+ icons on one token system, used by 1,200+ designers and developers.
