Mariusz Kozieł - Wizards and Kings

This special episode was recorded from the Buzzsprout podcast booth on Day 1 of Rails World 2025 in Amsterdam. Our guest, Mariusz Kozieł, is the CEO of Visuality, a Ruby on Rails agency based in Poland. We chat about Mariusz' career progression from developer, to engineering manager, to CTO, and now CEO. We also talk about his and Visuality's efforts to foster technical community with the Ruby Community Conference and Ruby Europe.

Thank you to Buzzsprout for sponsoring the Rails World Podcast program, and for providing us the opportunity to attend and record! 🙏
