Keith Daulton

An engineering leader who makes things people love to use

Fierce advocate for the people building products — and the people using them.

[ 01 ] About

Engineer
+ Designer.

Two-decade veteran of UI engineering, design systems and developer tools. Hands-on, opinionated, kind.

I build the tools that build the things
people love to use — and lead the teams
that ship them.
20+ Years shipping UI
60M+ GitLens installs
10+ Years of technical leadership

A hands-on leader in interface development and design. Over twenty-plus years I've built across developer tools, design systems, component libraries, e-commerce, and marketing content — including Chewy's Chirp design system, Spirit Airlines' booking experience, and the GitLens extension for VS Code.

I build systems that bring cohesion and accessibility for every — documentation, tokens, code — that engineering teams love to build with.

[ 02 ] The Story

Taking the
Scenic Route

The long way around — art to engineering, by way of everything in between.

For over twenty years, I was set on becoming an artist. A self-taught tool for putting my art portfolio online set me on a path I never saw coming — and every lens I picked up along the way is still in the work today.

Thinking,
made tangible.

Different problems, different stacks — all I'm proud of.

GitLens · 2026

The Commit Graph, Now a Workbench.

GitLens 18 turns the Commit Graph from a place you read history into a place you work — inspect, review, compose, and commit without leaving it. AI coding agents now first-class: live session status, an agent activity map, and a Kanban board for the work your agents are doing, all inside the IDE.

[ 02 ] Design Engineering · Chewy · 2021

Chewy's first hybrid mobile-first experience. The website detected the native app and adapted to it — matching its light or dark mode through a UA-string handshake, the company's first design-system-level dark mode. Three platform firsts in one surface: mobile-first, native-web hybrid, and dark mode.

[ 03 ] Design Systems · Chewy · 2021-22

A design system as a product. Chirp's component library in Storybook — one of four instances spanning legacy and modern Vue and React. Treating the design system like an internal product meant real documentation, real releases, and real customers: the engineers shipping on top of it.

Engineering leadership, design systems, developer experience — or just to say hi.

Let me know
what I can do
for you.

Based in South Florida, remote-first. If you're building something and think I could help, I'd like to hear about it.

Icebreaker: Ask me about my homebrewing hobby!
