Alexander Käßner

Product & Interface Design (B.A.)

Hi, I’m Alex – a young digital designer based in Berlin, Germany. I design products, interfaces, icons, mobile and desktop apps, websites, product videos, and create apps in my free time at pxlwaves lab.

For over ten years, I’ve worked with several companies and startups as a freelancer, built and shipped my own products, and co-founded an app company. I completed my bachelor’s degree in interface design at FH Potsdam.

In the past months I’ve built the future of design at Sketch in the collaboration team, before I had to leave the company. In the two years before, I’ve helped to ship Diagrams for Mac and shape the design of this great productivity app.
