Summary
🤩
RockstarKevin Papst is a founder and full-stack PHP engineer with 14 years of experience building and maintaining open-source web applications from Vienna. He founded Kimai, the widely used open-source time-tracking platform (and its Kimai-Cloud SaaS), and leads its ongoing product, performance, and UX improvements. As a hands-on maintainer he regularly ships backend refactors, LDAP and team management features, search and performance optimizations, and front-end polish like play/stop controls. His work spans Symfony-based admin themes, FreshRSS UI and i18n improvements, and deep PHP troubleshooting—demonstrating both product ownership and day-to-day coding. A long-time open-source advocate and PHP freelancer, he blends entrepreneurial leadership with practical engineering and a knack for small UX details that improve daily workflows. Outside work he’s a dad who deliberately chooses to run his own businesses and open-source projects rather than follow conventional paths.
