Top SchoolDima Tisnek is a senior software engineer with 15 years of cross-cultural experience across five countries and a strong track record building backend systems in Python and Linux. He co-founded a successful software company with €1M turnover and has since led and re-architected teams and products at companies from startups to Canonical, focusing on cloud deployment, API design, and systems engineering.
