Product Designer & Builder — Liège, Belgium
I take an idea all the way to a shipped product — solo and fast. A UX/UI foundation is what lets me direct AI toward quality instead of just prompting it. Three real products carry the proof.
01 — The shift
Writing the code stopped being the hard part. Knowing what good looks like — and steering a machine to it — became the whole job.
Anyone can generate a screen now. Generating the right screen, in the right order, with the right trade-offs, is a different skill — and it did not get cheaper.
That skill has a name in my trade: judgment. It is what decides which feature never gets built, which edge case matters, which number needs a source next to it. AI accelerates the part I already knew how to do; it does not replace the part that decides.
02 — How I work
01
Design decisions come first: what to build, what to cut, what "good" means here. The code follows from that — faster than ever, and pointed in the right direction.
02
Research, UX, interface, backend, deployment. One person holding the whole thread means no hand-off loss, no coordination tax, and a shipped thing at the end of it.
03
A demo survives one meeting. A product survives real data, real edge cases and real users asking where a number came from. I build the second one.
04
Years of teaching taught me to explain a technical trade-off to someone who does not want a lecture. You will always know what I am doing, why, and what it costs.
03 — Selected work
Not case-study theatre. These are live products I designed, built and shipped.
Product · solo build
Belgian investor tax & portfolio product
A domain where "roughly right" is worthless. Every figure carries its source, its "as of" date and a confidence level — because a number a user cannot audit is a number they cannot act on. Built solo, multilingual from day one.
What it proves
That I can make AI produce something correctness-critical and trustworthy.
Product · data at scale
A location-scoring index for Europe
Grades 51,000+ European municipalities from A to G using 12+ official data sources. The opinion is the product: score the place, not the listing. Shipped in four languages, ES/FR/IT/PT.
What it proves
Rigour and product thinking holding up at scale.
Consulting · ongoing
Product consulting with a live business
Ongoing product work with a real company and real constraints — roadmap, interface decisions, and the unglamorous calls that keep a product coherent as it grows.
What it proves
Not theory — how I work with a team today.
Private engagement
04 — Reach
Multilingual is not a line on a CV here — it is a market decision. Terragrado ships across several European countries because the person designing it can read the sources, write the copy and talk to the users in their own language. Same for the products I build with you.
05 — About
Self-taught, then obsessive about craft, then a teacher — and that last part changed how I build.
I started as a curious self-taught builder in Liège, taking things apart until they made sense. Craft came next: interfaces, typography, the difference between a screen that works and one that feels right.
Then I taught. Explaining a system to someone learning it forces you to actually understand it — and to drop the jargon. That is still the most useful professional skill I have.
Today I design and ship complete products, using AI as an accelerator on the parts I already know how to judge. Belgian roots, European scope.
