I am empowering people and organizations to reduce the complexity and risk inherent in the development of software-intensive systems by improving the way they design, evaluate and implement software architectures. This encompasses the enhancement of architecture-related methods and processes (e.g., technical debt management), the adoption of technologies (e.g., AI-based tools) and application of innovative architectural patterns and designs (e.g., AI-based architectures). I refer to all those activities as architectural change management.
During my career, I have gained more than 25 years of experience in strategic IT advisory, IT projects, enterprise and software architecture management. I have extensive practical experience in consulting on various large-scale projects and worked intensively with customers on innovative IT solutions. Particularly, I have a strong background on software architectures and software engineering. Thus, I have profound knowledge and experience in designing, evaluating and implementing software-intensive systems. Moreover, I closely collaborate with academia and focus on the transfer of cutting-edge research insights into practice. In this context I embrace complexity, new technologies and architectural challenges. However, I always observe new IT trends critically and put them into perspective.
