Designing and shipping digital products end to end from user research and interface design to live, working software in production.

How I work

Two ways to work together.

Pick the engagement that fits your stage. Both start with a 30-minute call.

01

Product Design in Figma

End-to-end product design — discovery, flows, UI, prototyping and handoff. I work as the embedded designer on your team for a sprint or a season.

  • UX & UI design
  • Interactive prototypes
  • Design systems & tokens
  • Design QA with engineering
02

Building with vibe coding tools

When speed matters, I design and ship the product myself. Real React, real database, real users, not a clickable prototype.

  • MVPs in 1–3 weeks
  • Marketing sites & landing pages
  • Internal tools & dashboards
  • Iteration after launch
About

A designer who also ships.

Book a call

I'm Romain, a freelance product designer based in Paris, France. For the last two years I've worked with early and growth-stage startups as their principal designer.

Figma is where I sketch and align with teams and Lovable, Cursor or Claude Code is where I turn those decisions into something real. Working across these tools keeps my designs honest and my shipped work opinionated.
