Senior Product Designer. The deliverable is a working prototype, not a mockup.

Rules and tokens first, so the model assembles instead of guessing.

[ How I Work ]

Years at early-stage, and larger organisations since, taught me to switch hats design today, code tomorrow, or do both on the same day.
Now it's usually one thing: I design in the code.

Agents do the research for me, following instructions I wrote. They get the sources and the rules once, then they work on their own.
The sharper the instructions, the fewer drafts come back, and the faster we can decide.

Figma stays. The visual detail and the craft happen there, and it holds what we agreed on.

I like thinking through problems with other people. Most good solutions come out of a brainstorm, not out of one head.

I work closely with the developers so the prototype sits as close as possible to what goes into production.
Where it makes sense and they want it, I ship the UI straight into the production code.

[ Tooling ]

I keep looking at what actually helps. What moves things forward I try out, and then it goes into how I work.

For example, the Figma CLI became part of how I work, because with it the work travels both ways between the terminal and Figma. I have rebuilt my own system several times since, so it doesn't only make things faster, it helps me decide.

[ What I Do ]

Product Design

Multi-hat Product Designer — research, planning, flows, dashboards, marketing pages, illustrations, animations.

Design Systems

Design Systems — tokens, components, patterns that compound.

Code

Code — implementation, pull requests, deploys. Design is where I start, not where I stop.
