About Paul


My interest is the area of Requirements Engineering, Systems Integration  & Software Engineering in tourism organizations in general and the cruise industry in particular. As a certified professional for requirements engineering (Advanced Level), I hold a 'Black Belt' in model-based Requirements Engineering.

My interests are located at the intersection between cruise tourism, business processes, enterprise integration patterns, model-driven requirements engineering, software engineering, and technology acceptance. I have been educated in a broad range of quantitative and qualitative skills at three European universities.

My work or work that I have contributed to has been published in peer-reviewed and renowned journals within the respective fields.

I am fluent in German, English, and Swedish. In addition, I am more or less fluent in UML 2, Python, Kotlin, Groovy, Java, Scala, Elixir, and a range of SQL dialects.

Skills & Experience


I consider myself a 'full-stack business analyst'. I possess a wide range of skills from requirements engineering, software engineering, business analysis and project management methodologies. I started writing code when I was 12 - the time I got my first Mac with HyperCard.

I have learned to dynamically deal with shifting priorities and expectations in uncertain environments.
