Hi there 👋

About Me

My name is Hans Knöchel and I'm the Co-Founder and CEO of Lambus, a collaborative travel platform. You can find more information on Lambus here!

Open Source

I spend some of my time in open source projects (roughly since 2014), primarily on iOS related projects as well as the Appcelerator Titanium ecosystem (acquired by Axway in 2016).


I am leading the maintainence of roughly 70 open source libraries (180+ in total), many of them iOS-, Android,- or Titanium related. If you like using one of my projects, I appreciate becoming a Github sponsor - more information can be found at my sponsors profile. You're great!
