Analyse, design, evaluate, iterate.

I started out with a master's in human–computer interaction ergonomics, and since then I have never stopped looking at new sides of the job.

For six and a half years at Murex I designed interfaces for trading, post-trade operations, treasury and risk management. These are dense fields, where the smallest ambiguity costs money.

Since July 2025 I have been working independently for several clients, owning the whole chain: framing the need, user research, wireframes, visual identity, design system, interface, then build and launch. It is the same method as before, analyse, design, evaluate, iterate, only over a wider scope, because no stage is delegated.
