Eight years designing apps and platforms.

Launching new products · improving what already ships · building the systems behind both

Modules — what I do
01

Interface design

Hierarchy, states, and behaviour across breakpoints, held together by a design system: components, tokens, and the variables development builds against. Accessible by default, not as a later pass.

02

Product thinking

Framing the problem before solving it. Understanding the constraints, deciding what to build first, and defining what success looks like.

03

User research

Choosing a method that fits the question, generative or evaluative, and running it without waiting for a dedicated researcher. Turning what comes out of it into decisions the team can act on.

04

Delivery

Specifying work at a level engineers can build from, understanding what is technically feasible, and reviewing what ships against what was designed.

05

Prototyping

Matching fidelity to the question. A sketch when the flow is in doubt, working code when the interaction is.

01 KYP 2024 — now First designer at a company, halfway through a frontend migration and a rebrand. A cleanup instead of a redesign, and what I would measure differently.

MVP · Platform 04 Piek 2020 Cashless payments for festivals with up to 20,000 visitors. A wallet, a till and an organiser portal, without plastic tokens.
