Vesper Design System
Vesper is Tenstorrent's product design system. It's built so engineers, and increasingly AI coding agents, can build coherent, on-brand interfaces without a designer in the room.
Vesper emerged from a pattern I kept seeing: our engineering teams were shipping internal demos that were built quickly and in isolation, and design was pulled in late when something suddenly had to look polished.
I diagnosed the issue as an organization-level design problem, brought it to leadership, and got buy-in. I designed the system and the first iteration of its structure, then partnered with two front-end engineers to make the system legible to the people building with it.
