Warsaw, Masovian Voivodeship, Poland
Summary
👤
SeniorMarcin Pietrzak is a seasoned WordPress developer with over a decade of hands-on experience building themes, plugins, and custom solutions for clients and public institutions. He runs iWorks, where he has developed commercial WordPress themes and plugins since 2000, and currently applies his expertise at the National Information Processing Institute. His background spans both product development and support—having worked on plugin development and 2nd-tier support at companies like OnTheGoSystems and Incsub—so he combines deep technical skill with user-focused troubleshooting. Marcin’s early career in web development, project and IT management gives him a rounded perspective on delivery, migration and operations. Based in Warsaw, he’s approachable for collaboration or consulting via email at his iworks.pl address. A less obvious strength is his long-term continuity: he’s sustained and evolved a solo product business alongside institutional roles for more than two decades.
