Hey folks!I'm Jean‑Francois Biere — hailing from Paris, based in Tallinn. A product designer and front‑end developer with 20+ years turning ideas into interactive, unique, bold experiences.
I work end‑to‑end: research, UX, high‑fidelity UI, design systems, then I build it with real, performant code. I love the messy middle where design meets engineering — that's where the magic is.
When I'm not pushing pixels, you'll find me sketching logos (yes, the bear is mine), exploring motion, and obsessing over the small details most people never notice — but always feel.
Design is everything.
What I do
[ services ]UI/UX Design
From research and flows to polished, high-fidelity interfaces that convert.
Design Systems
Scalable component libraries and tokens that keep teams fast and consistent.
Creative Front‑End
Hand-built, performant interfaces — React, WebGL, zero dependencies, the fun stuff.
Motion & Art Direction
Identity, motion language and the details that make a brand feel alive.
AI‑Assisted Workflows
AI in the loop — prompt‑driven prototyping, agentic coding, faster shipping without losing the craft.
Empathize — Define — Ideate — Prototype — Test…
