Summary
👤
Senior🎓
Top SchoolFelix Wolfsteller is a seasoned backend engineer with 14+ years building resilient, open-source-first systems for nonprofits, cooperatives and small networks from his base in Beetzendorf, Germany. He combines hands-on server administration and SysOps with backend development, having founded econya to provide FOSS-driven software and infrastructure services while managing community networks for a 100+ resident ecovillage. At betterplace.org he progressed from developer to lead backend engineer and now continues to apply that operational rigor at about source GmbH. Felix favors collaborative, transparent development — he treats copying and reuse as enablers of rapid innovation and contributes practical example server code to projects like roar. Deeply community-oriented and non-relocatable by choice, he prioritizes humanist causes and sustainable tech over VC-driven metrics. Colleagues know him as pragmatic, honest and accessible, with a dry sense of humor and a willingness to take on full-stack operational challenges.
