Summary
I take software to a whole new level with artificial intelligence.
Applying artificial intelligence is a challenge. As an expert in this field, I ensure that your company makes the most of AI. I do this with tailored strategies for introducing and using AI in your business, and by implementing solutions that align with your company's specific needs and goals.
My journey started 25 years ago with my diploma thesis in collaboration with an IT startup and the German Research Center for Artificial Intelligence (DFKI). Since then, I have been developing software in artificial intelligence and big data. As a software architect, I took responsibility for significant IT projects, including the architecture of a highly scalable and available big data system and a large-scale strategic cloud transformation project.
With my deep understanding of the technology landscape and solid knowledge in areas such as machine learning, deep learning, and natural language processing, I help your company gain a technological edge to stand out in today's business world.
My more than 15 years of leadership experience enables me to lead teams flexibly while considering individual work styles. I can do this in both traditional structures and agile environments.
As a consultant, I regularly give presentations and guest lectures at universities. My particular strength is explaining technical topics in a way that even non-IT experts and laypeople can follow. This allows for better alignment of expectations and goals between management and departments.
