Hi, my name is Dennis


1 minute


or »wottpal« which is a spooner­ism1 of »pottwal« — the German word for sperm whale. I’ve heard it for the first time in the famous movie AmĂ©lie when I was a child. It was the name of one of her gold­fish. 🐳

I design & build web­sites and soft­ware. More­over I’m deeply inter­ested in really all kinds of tech­nol­ogy. Lately I’ve also dis­cov­ered the artist in me. I don’t post any­thing on Insta­gram and hate Face­book but you can find me on Twit­ter. If you want some more insights about how my life went off so far — just conit­inue read­ing.

  • born in 1993
  • left my home­town and went to a sci­en­tif­i­cally spe­cial­ized board­ing school in 2008
  • trav­elled through India after school and did some vol­un­tary work in 2012 – 13
  • study­ing com­puter sci­ence since then while work­ing half-time as a web-devel­oper and designer


  • always striv­ing for per­fec­tion
  • a sense of beauty as well as design-expe­ri­ence for var­i­ous plat­forms2
  • in-depth knowl­edge of var­i­ous web-tech­nolo­gies3
  • fun­da­men­tal under­stand­ing in all sub­jects of com­puter-sci­ence4
  • basic devel­op­ment expe­ri­ence for iOS and macOS


I’ve espe­cially built this web­site for show­ing off some work I am up to and also fea­tur­ing some work I did in the past. But it takes some time to pre­process all that and give it a nar­ra­tive so it’s inter­est­ing for you, the reader. If you want to stay in the loop — sub­scribe to my very infre­quent newslet­ter. You prob­a­bly should if you made it so far. 🙃

  1. <p>A <strong>spoonerism</strong> is an error in speech or delib­er­ate play on words in which cor­re­spond­ing con­so­nants, vowels, or mor­phemes are switched.

  2. <p>I have designed prod­ucts for the web as well as iOS, macOS and cross-plat­form appli­ca­tions. Par­tic­u­larly in the German med­ical sector. &#160;<a href=«#fnref1:2« rev=»footnote« class=»footnote-backref«>&#8617;</a></p>
  3. <p>I know a lot about HTML, CSS and JavaScript and how the web works. I reg­u­larly visit web-con­fer­ences all over the globe.&#160;<a href=«#fnref1:3« rev=»footnote« class=»footnote-backref«>&#8617;</a></p>
  4. <p>Whoa, better read <a href=»https://en.wikipedia.org/wiki/Computer_science«>this</a> for a rough out­line. Recently I am more and more inter­ested in machine-learn­ing topics and gen­er­a­tive art.&#160;<a href=«#fnref1:4« rev=»footnote« class=»footnote-backref«>&#8617;</a></p>
