Rockstar🎓
Top SchoolOndřej Machulda is a Lead Engineer and team leader with 14+ years of hands-on experience building reliable web applications and platform services, and over 20 years of PHP experience.

Comfortable across Linux, Docker, and CI/CD pipelines, he focuses on reliability, automation and product-minded engineering rather than just shipping features. He has driven architecture and shared-platform initiatives (cookie-consent and GIS services) across companies and currently leads engineering at Prusa Research while maintaining freelance and OSS commitments. His open-source contributions include stabilizing widely used projects like php-webdriver and improving tooling for Symfony coding standards, reflecting a pragmatic approach to long-term maintainability. Colleagues rely on him for technical leadership, cross-team coordination and raising engineering practices through training and automation.
