Top SchoolJan Klopper is a pragmatic application developer, DBA and project lead with six years of formal experience and two decades of entrepreneurial engineering practice building high-performance, high-availability web systems on commodity hardware.

Skilled across PHP, MySQL, Linux/x86 architectures, virtualization and failover design, Jan blends hands-on implementation with operational ownership and a focus on measurable reliability. He also founds and coordinates community tech initiatives (eth0, Startup Weekend Leeuwarden) and runs energy-transition and infrastructure ventures, reflecting a practical, systems-level approach to problem solving. An engineer who prefers building resilient clusters over relying on opaque platforms, he pairs entrepreneurial grit with public-sector security expertise.
