sheet 01 — design & development studio · JD/2026

We build the tools that good work is made with.

The studio of Ruud and Ruby — she designs, he builds, and everything you see here is our own work, down to the tools behind this site.

Two signatures

Design

Identity, interface and interaction — drawn by Ruby. From first sketch to a living design system where every decision has a name.

From the studio

The tools are on the table

No portfolio talk: these are the tools and libraries we use ourselves, daily.

component. · public

Component library

Every interface building block we make, documented and reusable — linked straight to Figma.

component. · public

Icons & assets

Hand-drawn icon set in multiple styles, editable down to the SVG path.

studio. · internal

Design-DNA scanner

Reads the visual identity of an existing site — colour, rhythm, structure — as the starting point for a redesign.

studio. · internal

UX-audit builder

Structured audits with findings by severity, category and recommendation — shareable as a report.

"Details are not details.
They make the design."

The duo

Small enough to make everything ourselves

We believe the best digital products are made where design and engineering are not handed over, but pass through the same hands. That is why we build our own tools — and why this site is the first exhibit: every component, colour and typeface comes from our own system.
