Writing about web craft, design systems, and the occasional rabbit hole.

A developer and designer thinking out loud about how interfaces communicate — from component APIs to the grammar hiding in our design tokens. Based in London, working on tooling for design systems at scale.

What Senior Actually Means

Seniority isn't a measure of how much you know. It's a measure of how well you know what you don't know — and how systematically you close those gaps before they become incidents.

The Case for Boring Technology

Every year, the same conversation: should we use the shiny new thing? Five years in, I've learned to love the boring choice — not out of cowardice, but out of respect for the people who will maintain this code after I'm gone.

Design Systems Are Grammar, Not Paint

A design system isn't a component library. It's the grammar of a visual language — and like any grammar, it only becomes interesting once people start bending the rules.

AI Assistants and the Context Window

The context window is not memory. Three habits I use to work with the constraint instead of against it — and why each is just structured omission in disguise.

Calm Defaults

A pattern for restraint — shipping software with a quiet first impression, restrained feature scope, and the highest number of users who never notice the product exists.

Token-as-Grammar

A finite set of choices that constrains composition the way grammar constrains a sentence. The strong version of this pattern asks you to remove tokens, not add them.
