Top SchoolPiotr Macuk is a seasoned software leader and founder with over 20 years of hands-on experience building scalable web applications and leading engineering teams. As Founder and Technical Leader of Konfeo since 2012, he turned an event registration idea into a production SaaS platform serving complex ticketing and registration workflows. His background spans startup and enterprise contexts, including staff-level engineering at Shopify and senior full‑stack roles at Hopin and Rebased, demonstrating fluency across Rails backends, React frontends, CI/CD, security audits and spatial data visualization. He has deep experience with high‑traffic, complex domain systems from medical registries to large-scale BIM projects, often combining architecture, project management and developer mentorship.
