Owner at Killjoy Manufacturing
Fort Collins, Colorado, United States
Summary
🤩
RockstarPaul Hummer is a pragmatic software engineer and founder with 17 years of experience spanning Linux kernel subsystems, backend services, mobile and cloud DevOps, and manufacturing-grade hardware work. As a former tech lead at InfluxData he helped build the Flux query language and improved the InfluxDB read path, and his open-source contributions include maintenance and testing improvements to widely used projects like flux and dulwich. He favors doing the right work at the right layer—prioritizing stability, maintainability, and clear product intent over language or framework dogma. Paul now runs Killjoy Manufacturing, applying CAD/CAM, CNC and 3D printing to electric motor retrofits and industrial parts, and consults on simplifying cloud infrastructure to reduce cost and operational complexity. Colleagues describe him as quietly effective and independent-minded—“a loner, Dottie” who delivers practical, long-lived solutions.
