01

The problem

Every screen looked and felt slightly different. Engineers were rebuilding the same primitives. Feature velocity was hitting a wall.

02

Approach

Introduced a token system with light and dark themes, wrote a 40-primitive component library, and paired every component with usage docs.

03

Outcome

Feature velocity increased 4× in the following quarter and design and engineering finally spoke the same language.

Let's build something

Have an ambitious idea? Let's turn it into a product.

I take on a small number of engagements each quarter. If you're building something meaningful, I'd love to hear about it.
