About me

Hi! I'm Dieter Peirs, an interface designer and front-end developer.

For the past 18 years, I've worked as a designer on identity, print and web projects. Currently, I focus on websites and applications as an interface designer and front-end developer.

I believe the future of the web is sustainable, simple to use and accessible to all. To achieve this, I balance aesthetics, experience and efficient code. I collaborate with authentic brands, businesses and start-ups to solve design problems which benefit their business and the end-user.

On the side, I'm conquering my fear of heights by climbing up and down walls. I enjoy noodling on my guitar and making silly noises with my synthesiser.
