Raphaël Berset

About Raphaël

Raphaël Berset is a frontend engineer at Atelier Léman in Geneva, where he builds the kind of web interfaces that feel inevitable: fast, accessible, and quietly well-constructed. With one foot in engineering and one in design, he acts as a translator between the two — turning design intent into systems that scale without accumulating debt.

He has led teams building component libraries for international clients and is a fixture in the web community through talks, workshops, and open-source work. His quiet obsession is making the web faster and more inclusive for everyone, on every connection.
