Jacek Foremski is a Principal Software Engineer based in Krakow with 11 years of experience designing and delivering backend systems, primarily in PHP and Symfony, and a track record of leading teams to production-ready software. He combines hands-on kernel-level contributions (notably improving eZ Publish core components and templating robustness) with architecture and delivery responsibilities at companies from startups to Atlassian. A clean-code evangelist and agile proponent, he mentors engineers, builds CI/CD-driven infrastructure, and translates product needs into maintainable systems. Comfortable exploring Java and Python, he brings practical polyglot curiosity to solve integration and reliability challenges. His background includes both hands-on development and people leadership, having moved from head of web development to principal and team lead roles. Colleagues describe him as a continual learner who makes new techniques part of his engineering process rather than keeping them theoretical.
