About Me

I'm Adrian Sieber (as you might have figured out by now…) and I'm a software engineer and entrepreneur living in Germany.

Currently I'm the CEO of Feram (feram.io) and we're developing Airsequel (airsequel.com).

Previously I studied IT-Systems Engineering at the Hasso Plattner Institut.

Hobbies

Apart from work I used to make a lot of music, both electronically and with traditional instruments like Saxophone, Piano, Guitar, and Ukukle. However, nowadays I barely find the time anymore, but when I do I prefer my new favorite instrument, the LinnStrument.

As sitting in front of the computer the whole day is rather unhealthy I regularly go out for runs. In addition I like to go skiing in winter and sailing in summer.

Supporting Good Causes

True to the motto "Put your money where your mouth is" I join nonprofit organizations supporting my beliefs and donate regularly to them (you should too 😉):

Atmosfair - Compensating around 22 Mg (1 Megagram == 1 Ton) of CO₂ per year.
Klimaschutz im Bundestag - German organization demanding clear climate goals from the German government.
FSF - Free Software Foundation.
IBKA e.V. - International League of non-religious and atheists.
Pro Rauchfrei e.V. - German organization to protect non smokers.
The Dozenal Society of America - Promoting the base 12 number system.
The Internet Archive - Archive of internet sites, texts, and multimedia
U.S. Metric Association - Promoting the metrication of the U.S.
Wikimedia e.V. - German branch of the Wikimedia Foundation.
Zwanzigeins e.V. - Fix pronunciation of numbers in German (twenty-one instead of one-and-twenty).

I also regularly donate to free / open source software projects:
