Summary
I take software to a completely new level with the help of artificial intelligence.
Implementing artificial intelligence is a challenge. As an expert in this field, I ensure that your company makes the most of AI. I do this through my tailored strategies for introducing and using AI in your business and by implementing solutions that are aligned with your company's specific needs and goals.
My journey began 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've been developing software in the fields of artificial intelligence and big data. As a software architect, I took on responsibility for major IT projects, including the architecture for a highly scalable and available big data system and a large-scale strategic cloud transformation project.
Thanks to my deep understanding of the technology landscape and solid knowledge in areas such as machine learning, deep learning and natural language processing, I deliver technological advantages for your company to succeed in today's business world.
My more than 15 years of leadership experience enable me to lead teams flexibly and with respect for individual working styles. I can do this in both well-defined structures and agile environments.
As a consultant, I regularly give presentations and guest lectures at universities. This is where my special strengths lie: I explain technical topics in a way that even laypeople and non-IT specialists can easily understand. This allows for better alignment of expectations and goals between management and technical departments.
