About me
My name is Lutz Hühnken. I'm currently on a mini-sabbatical, taking time to rest, reflect, and prepare for the next chapter in my career.
Previously, taking on the roles with titles such as Head of Engineering or Chief Architect, I lead the development of software for container shipping, online retailers, financial institutions, cruise ships in-cabin entertainment, and others. My current focus is on event-driven architecture, highly available and scalable systems, domain-driven design, and the intersection of architecture and organization.
