There is no clear line between "designing" and technically implementing a project. There'll always be decisions made by developers that heavily impact user experience, since It's impossible to design every aspect of an application in advance in a design tool. This is where I specialise, fully comprehending both: user needs and technical possibilities. My dual background in Design and Technology allows me to talk eye-to-eye with teammates (and clients) who have their focus in either fields.

I'm a Design Generalist focusing on UX and UI with a passion for Web Development. Creating user-centred digital products, from scratch to prototype to mirror-polished. Building bridges between Designers and Developers. I have a degree in Design (German Diplom) and I've been building websites for over 10 years now.

Find me on LinkedIn, Twitter, Gitlab or Github.
