Hello, my name is Dennis Flinsenberg and I design ugly and highly unusable user interfaces. Yeah, not really. In my spare time I dabble in photography on Instagram500px & Flickr, listen to a lot of music, post gifs and memes on Twitter and occasionally post stuff on Dribbble. I’m also an avid tv show and movie watcher.
