Summary
🤩
Rockstar🎓
Top SchoolJean-marcel Flach is a pragmatic software engineer with 11 years’ experience building and evolving monitoring systems, having developed core functionality for prominent open-source projects like Icinga2. He moved from hands-on C++ and Python development at NETWAYS into product-focused roles at Paessler, where he progressed from developer to product owner and gained strong insight into customer expectations for monitoring software. He left university early to pursue an apprenticeship and has translated that non-traditional path into practical technical depth and product instincts. Jean-marcel combines backend systems expertise—character encoding support and notification logging changes in Icinga2—with growing leadership and product ownership skills. Based in Nuremberg, he’s comfortable bridging engineering and customer-facing perspectives to turn real-world needs into reliable features. Colleagues describe him as a developer who thinks like a user and a product owner who understands the implementation details.
