The name’s Felix.

On this site, I share my works, ideas and services.

Below are some of my projects and what lessons to glean from them. I hope you find something worthwhile here.

About me

In my day job, I blow stuff up. In my private life, I try to mend things. I enjoy organizing and leading people just as much as listening and learning from anyone. I've officially been named a hero, which is neat.

Born sometime during the ‘90s in the bountiful farmlands of northern Germany, now residing in warmer climates.

I like the idea of personal homepages, diversity of opinion and approaches, instead of feeding the Silicon Valley content silos with ephemeralities.

Hobbies & Mojo™

I like being in nature a lot. Camping, running, hiking, rock climbing, … those are my idea of a fun time.

Apart from those, I also tend to enjoy:

Some moving pictures I think are decent:

Projects & Writing

I find myself having to have a "project" to stay sane in my free time. My woodworking, art etc. are probably junk, but give me zen-like pleasure. The world will also never be set on fire by me as a writer, yet there's some of my writing I'm modestly proud of.


  • Have a look at the Projects page for a birds-eye view of some of my better-known works.

Mastery of machines

While I am apparently not made for life in an office, I do enjoy telling computers what to do. My involvement with the Open Devices Project has won me some accolades, and I have a knack for digging in and figuring things out.

Code & tech writing, hosting

Mobile ventures

  • Have a look at the Mobile Projects page for an overview of my work in the Android-adjacent sector.
  • Open Devices Community Page - I maintain an unofficial page about the Open Devices project for newcomers
  • AOSP Contribs - Commits I have made to Android, which are most likely running inside your phone right now.

Tango & older ventures

I used to have a serious infatuation with Argentine Tango a good while back.
Here are some remnants:

I enjoyed taking responsiblity when working with my peers at my old student union. At the “Fachschaft W” — which is also a legally registered club of about 90 members with discrete finances — I ran:

  • Finances as CFO, as such also part of the board (ret. June 2018)
  • Tech infrastructure, including Cloud Document Sharing, Knowledge Management, Homepage, Business Application Suite
  • Office affairs


People, sites and organizations that I think are interesting:

  • Idle Words - Maciej has spent his academic career studying writing and it shows. His early travel reports are a delight; his more recent posts delve deeply into crucial issues such as progressive election campaigns and the real powers that govern technology.
  • Aaron Parecki - Someone who lives for and on the IndieWeb. It is nice to see the possibilities of federated technologies in real-world use.
  • Bret Victor - Visionary. His interface works are legendary and have paved the way for radical rethinking of human-machine interaction.
