Heyho! I am Holger Rapp from Germany. I have been open source contributor and enthusiast for over 20 years and have had the great fortune of starting a few successful projects.

• Widelands, a free build up strategy game that has seen hundreds of contributors and millions of players. https://github.com/widelands/widelands.
• UltiSnips, the Ultimate snippet engine for Vim, used by thousands, contributed to by > 100 people. https://github.com/SirVer/ultisnips
• Cartographer, a former Google project helping robots understand and navigate their world. https://github.com/cartographer-project.

I try to keep my projects maintained, even though my day job leaves me little time. If you appreciate any of my work, I'd appreciate a thank you, sharing of my work or a bit of sponsorship, maybe a coffee per month?
