Senior🎓
Top SchoolNiklas Gerstner is a full-stack software engineer based in Munich with 11 years of hands-on experience building scalable web platforms and developer tools. He combines entrepreneurial drive—running Krymo Software and a profitable, high-scale game server hosting platform—with deep operational experience in containerization, Kubernetes, and cloud-native workflows. Niklas has shipped over 30 commercial plugins, supported 450+ clients, and contributed backend fixes and enhancements to well-known open-source projects like WoltLab Suite Core. His corporate work spans CHECK24 and AurumCars, where he modernized frontends, implemented robust after-sales systems, and helped deliver a public-facing betting game that attracted millions of users. Equally comfortable leading small teams or working solo, he pairs pragmatic product focus with attention to observability and reliability. An uncommon detail: he built a Docker Compose configurator that actively helps 1,500+ server admins manage Minecraft servers in real time.
