Hello, I'm Jens

User Experience, Code & Design

Who I am

Hello! I’m Jens. A User Experience Specialist and Front-End Developer based in Bonn, Germany.

Apart from that I am curious, mindful, always learning, a geek, occasionally a bit nerdy, but down-to-earth with my head in the clouds sometimes and I like trying out new lemonades.

Wanna know more?

Although I’ve been developing software professionally for nearly 20 years now, I still love trying new things and thinking outside the box. This is one reason why I started iOS app development in 2013 and migrated from Windows to Mac for private use.

I’m interested in working with companies who care about the people around them and love the work they produce.

And even more?

My roots lie in the area of electrical engineering. In 1997 I decided to make my hobby a profession and I am working as a software developer since then. Currently I am self-employed and working on new projects, where I’m developing apps for the iOS platform, creating user experiences and user interfaces (UI/UX) as well as interaction design.

After working in Software Development for over 15 years always being passionate about the beauty of user interfaces, I am now focussing on User Experience Design and (UX) and User Interfaces (UI). Since 2012 I’m working as a User Experience Specialist (since 2014 Senior) and crafting concepts for web and mobile apps. Mostly concerning interaction design, visual design, UI mockups and asset creation.

In my spare time I do things like: Crafting apps, playing the guitar and ukulele, biking mountains, hiking / traveling, practicing Yoga (sometimes I even write about my experiences) and doing yoga. And I began creating audio books from the Gutenberg Project (https://mach-die-biege.de/category/lesen/).
