Designing interfaces with the rigor of engineering.
Shipping them with the taste of a designer.

I'm James — ten years building product surfaces for early-stage teams from Austin, TX. Consulting on the hard parts. Selling the parts you can reuse.

What I do ⟶ 03

Three practices, one engineering mindset

01 — Product strategy

Decide what to build before pixels move.

Two-week sprints with founders to pressure-test the product, cut scope by roughly 40%, and ship the surface that actually moves the metric. No deck theater.

Discovery sprintsPricing & packagingRoadmap pruning

02 — UI architecture

Component graphs your engineers can actually read.

Typed primitives, predictable state, zero one-off cards.

03 — Design systems

Tokens, primitives, and the docs that keep them honest.

Built in Figma, shipped to code in the same week.

Around 94% of engagements end with a system the in-house team keeps building on without me. That's the bar.
