THE DESIGN PRACTICEOF GUILHERME COELHO

Tools for humans.

We're a design partner for teams building powerful tools in complex domains. Together we clarify what the product is, where it's going, and how it looks — so they can build even faster without imploding in the age of AI coding.

Thesis

AI lets teams build incredibly fast, but speed without structure just accelerates you in different directions. When the bottleneck isn't coding anymore, having a clear product mental model that everyone, human or not, can follow is essential.

Working modes

Plan once

A one-time deep dive. Define your product's DNA so you can press down on the throttle. Mental model + sitemap + signature patterns + component library. Then we're out.

Build forever

We embed with your team. We'll design features, implement UI, review PRs and refactor the experience. Ongoing support you can dial up or down. Instant design firepower.
