About Me
I am an IT professional from Germany with a strong focus on corporate software architecture. As a freelancer for many years I have supported several clients, developed enterprise architectures with and without teams in a wide range of industries and technologies. In the last years I worked as CTO and head of an IT department. Check out the portfolio section to learn more.
The business changes. The technology changes. The team changes. The team members change. The problem isn't change, per se, because change is going to happen; the problem, rather, is the inability to cope with change when it comes. Kent Beck
What I Do
Software Architecture
Companies nowadays work to a large extent with standard tools such as an ERP, CRM, financial accounting etc. Therefore, the architecture includes the selection of software, its seamless integration and the development of business-specific systems.Team Lead
Over the years of I worked with team sized between 2 and 25 people. Developers, DevOps, Administrators, Service Desk as well as projects I did more or less on my own. From Kanban to Scrum, waterfall to agile projects: there is no single true way to get the work done.Portfolio

Developer / IT ProfessionalApart from learning about digital technology and computer science in my training as an electrical engineer, I have no official training or school qualification as a developer. In the 20 years I have read quite a few books and intensively studied their domain for each customer or employer. This ranged from physics calculations for heat consumption to e-commerce processes to printer cartridges. In my work in teams of various sizes, I have found few gaps that would have justified a computer science degree. Domain Driven Design, SOLID, Kanban, Scrum, BPMN are natural for my daily work.
