Summary

As a recognized expert in artificial intelligence, I also have in-depth knowledge of cloud and application architecture for AWS and Azure. With more than 25 years of experience in AI, Java, Python, C, C++, JavaScript and many other programming languages, I am known for delivering high-quality solutions and leading teams to success.

My journey began with my diploma thesis in collaboration with an IT startup and the German Research Center for Artificial Intelligence (DFKI). Since then, for over 25 years I have been developing software in the field of artificial intelligence and big data. As a software architect, I was responsible for major IT projects, in particular for the architecture of a highly scalable and available big data system and a large strategic cloud transformation project.

Since 2012, as a system architect I have been shaping cloud architectures on AWS and Azure, leveraging their scalability and security features to build robust and efficient systems. My focus on scalable, resilient and secure solutions enables me to optimally deliver cloud-based applications.

As a tech lead on demand, I have excelled by guiding and mentoring cross-functional teams, ensuring effective collaboration and fostering a culture of innovation. My coaching services and workshops have helped my clients realize their potential and implement best practices in software development.

I have a strong foundation in artificial intelligence, cloud, software architecture and agile methods.
