Good interfaces
are invisible.

Good AI
is inevitable.

I build both.

(01) — Manifesto

I build products end to end — the interface people touch, and the AI they never see. Designed to disappear. Engineered to last.

(02) — Profile

Ex-Alibaba & AliExpress. 16 years making digital products — designing the interface and building what's behind it, AI included.

(03) — Now

Right now I'm vibecoding full products from scratch — iOS, macOS, web — and wiring the AI inside them: agents and automations that actually run.

End-to-end products

From first flow to shipped — design, front-end, backend and AI, by one person.

AI agents & automation

Put n8n, Hermes and OpenClaw to work — automate the busywork, not the people.

Fractional product design

Embed with your team and move fast — strategy, UX and UI on demand.

Let's make something that works.

Design only, or do you build too?

Both. I take products from the first flow to shipped — interface, front-end, backend and the AI in between.

Can you automate something in our business?

Usually yes. I build AI agents and automations (n8n, Hermes, OpenClaw) that take over repetitive, rules-based work.

How do you engage?

Project-based or fractional / part-time. Happy to start with a small, scoped piece so we both see the fit.

Where are you based?

Lisbon, Portugal (WET). I work remotely with teams in any timezone.
