Summary

Digital technology fascinated me as a child. I have kept this passion for all things digital and their impact on our society to this day. As a consultant, analyst, and project manager, I help small and medium-sized businesses make the most of digital transformation by building more digital and innovative skills. This especially covers data organization, process optimization and automation, and work organization. As a software engineer and software architect, I also put resulting projects into practice based on your vision and optimized for the individual needs of your workforce, or I create clear prototypes and MVPs. Thanks to my experience in IT security, the principles of Security-By-Design and Privacy-By-Design are always front and center in all these activities.

AI? Sure. Computer vision in particular and machine learning in general have been part of my work since university. Generative AI has not only become an important tool in my daily work but also part of my solution portfolio. Trustworthy AI and compliance with the AI Act? Of course also a given.

With my knowledge of behavioral and communication psychology and my ability to explain technical matters simply and correctly, I always bridge the gap between technical and professional stakeholders. With more than 20 years in the IT and software industry and as an active member of professional bodies like the German Informatics Society (GI), the Association for Computing Machinery (ACM), and the IEEE, I can easily cover both the business and technical sides of digitization in a practical way.

What does your tomorrow look like? How do you solve the complex challenges of the digital age? How will you become digitally agile? I look forward to answering these questions with you and guiding you on your path to the digital future.

Skills

To Start, The Answer To The Question "Can You Also [X]?" Is In Many Cases "Yes." I Have No Problem Diving Deep Into Other Frameworks, Libraries, And Standards Before A Project Within The Technologies And Programming Languages I List. That's Part Of My Job. You May Also Notice That I Deliberately Left Out Cloud Services Like Azure, Aws, And Gcp From My Skill Profile. The Sheer Number Of Specific Services On Those Platforms Makes Asking Whether I Generally Master The Platform Seem Pointless. If You (Or Your End Customer) Specify Which Services My Role Should Use Or Access In The Project, I Can Certainly Give A Meaningful Answer.

Also Note That For Clarity I Refrain From Listing Every Microframework And Library Here. You Can Assume I'm Familiar With Common Libraries For Data Management And Querying (Redux, Zustand, Mobx, React-query, Backbone.js, Zod, Pydantic, Mongoose, Sqlalchemy, Entityframework, Etc.) If The Corresponding Framework Or Language Is In The List Below.
