Summary
👤
Senior🎓
Top SchoolJan Klat is a pragmatic technology leader who heads Product Technology for Dr.Max, Europe's largest pharmacy chain, overseeing engineering, DevOps, QA and platform teams across six countries and ~120 engineers. With a decade-plus career that began in hands-on PHP development and grew through architecture and org leadership, he excels at translating between business priorities and engineering realities to ensure teams build what truly matters. He led the multi-country e-commerce platform from its early days as first solution architect to cloud modernization and composable commerce adoption as Group Head, driving FinOps and scalable platforms. Early work in observability and active contributions to the Prometheus ecosystem reflect a deep operational mindset—he even added sysfs-based network parsing to a well-known Prometheus library. Colleagues describe him as builder-first: he values teams that ship, platforms that scale, and technology that serves product goals rather than the reverse. Based in Prague, he combines pragmatic delivery experience with strategic platform thinking across complex, regulated retail environments.
