About Me

I am driven by the goal of achieving project success. Recognizing that it requires collective effort, I consistently go the extra mile to make things happen.

Collaboration and dedication are at the core of my approach, as I work alongside teams and stakeholders to overcome challenges and deliver successful outcomes.

Software development has always been my passion since childhood, even before computers were accessible to the public.

I worked tirelessly to become a skilled software developer, recognizing that exceptional software requires a solid architecture.
This led me to specialize as a high-skilled software architect, understanding the critical role architecture plays in creating outstanding solutions.

To ensure a comprehensive approach, I also ventured into business analysis, recognizing the importance of thorough requirement analysis and aligning software solutions with business needs.

Over the years, I have embraced multiple roles - sometimes simultaneously, constantly honing my skills through practice and training, much like a professional athlete.

With over 30 years of experience in the software development industry, I bring a wealth of knowledge and expertise.

Originally from Germany, I have been living and working in the beautiful north-east of Sweden for the past two years, residing in a small cottage near the Baltic Sea (with fiber high speed internet).

As a remote worker, I cater to clients from diverse countries, offering my services with a pro-active and entrepreneurial mindset.
While I primarily communicate in German and English, I adapt to different project requirements.

In addition to my innovative skills, I hold steadfast to timeless values of integrity, responsibility, and reliability. These principles guide my work and ensure a strong foundation for successful collaborations.

In my spare time, I enjoy carpentry, riding my BMW 1200 motorcycle, and sailing on my motorboat in the Baltic Sea.
Additionally, always honing my IT skills remains an important part of my hobbies during the long and dark winters here in Sweden.

My children have grown up and are now pursuing their own careers.
