Frederic realizes that websites are a great deal more than their visuals. When he makes designs with code, he gets everything right. Having been a trusted advisor to companies like PwC, Wavecast, and Kunstmaan, Frederic has proven himself capable of taking on projects of any size. He excels at breaking down static designs into dynamic web components that are flexible, reusable, and bulletproof.

Tiny Tarantino
Tiny Tarantino gathers the best kid-friendly videos from Vimeo and YouTube in one place. It's intended for kids' use, and it offers an alternative video platform to YouTube where every available video is hand-picked by either you or us.

Tiny Tarantino is a personal side project of mine.

I built the front-end template for an enterprise-grade open-publishing and live-broadcasting platform. The platform strives to deliver world-class thought leadership campaigns in real time with high levels of engagement.

This template was constructed from a utility framework of Atomic web components that I developed within Pattern Lab. All of the web components within this framework adhere to material design guidelines.

Nazka Mapps
I've built both the front- and back-end for Nazka Mapps' online home. The interactive map applications of Nazka help you to get your message across, placing a particular emphasis on accessibility, simplicity, and user-friendliness.
