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, I have been developing software in the field of artificial intelligence and big data for over 25 years. As a software architect, I was responsible for large IT projects, especially the architecture of a highly scalable and available big data system and an extensive strategic cloud transformation project.
Since 2012, as a system architect I have played a key role in shaping cloud architectures on AWS and Azure by leveraging their scalability and security features to build robust and efficient systems. My focus on scalable, resilient and secure solutions enables me to deliver cloud-based applications optimally.
As an interim tech lead, 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 unlock their potential and implement best practices in software development.
I am passionate about using technology to drive business growth and I look forward to bringing my skills and experience to your company.
