# Who’s that d11n guy?
Hi, I’m Dennis, a freelance software developer from Bremen, Germany. This website is a collection of my the Bitcoin related content and code I write.
After ten years of freelancing I decided to go full-time open source and do what I love most: Working on open software and Bitcoin related projects to do my share in making the world a better place by spreading the ideas of individual freedom and sound money.
Besides working on my own projects I am involved with UI/UX and documentation improvements in several projects like BTCPay Server and the Wasabi Wallet. Together with my peers Markus, Gigi, Fab and Daniel I co-host the Einundzwanzig podcast for the german speaking Bitcoin audience.
If you like what I do and want to support my efforts, please consider donating: I care less for the money, but really appreciate the gesture, your kindness and the virtual pat on the back!
