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 leverage the benefits of digital transformation through stronger digital and innovative capabilities. This especially covers data organization, process optimization and automation, and work organization. As a software engineer and software architect, I also implement resulting projects based on your vision and optimized for your staff's individual needs, or I create meaningful prototypes and MVPs. Thanks to my experience in IT security, the principles of security-by-design and privacy-by-design are always at the forefront of everything I do.
AI? Sure. Computer vision in particular and machine learning in general have been with me since my studies. Generative AI has become not only an important tool in my daily work but also part of my solution portfolio. Trustworthy AI and compliance with the AI Act? Of course, they are a given.
With my knowledge of behavioral and communication psychology and my ability to explain technical issues clearly and accurately, I always manage to mediate between technical and business stakeholders. With more than 20 years in the IT and software industry and as an active member of professional associations such as the Society for Informatics (GI), the Association for Computing Machinery (ACM), and IEEE, I find it easy to cover not just the business but also the technical side of digitalization in a comprehensive and practical way.
What does your tomorrow look like? How are you solving the complex challenges of the digital age? How will you become digitally agile? I look forward to answering these questions together with you and supporting you on your path to a digital future.
Skills
First Off, The Answer To The Question "Can You Also Do [X]?" Is Often "Yes." I Have No Problem Getting Up To Speed On Additional Frameworks, Libraries, And Standards Before A Project, As Long As They Fall Within The Technologies And Programming Languages I've Listed. That's Part Of My Job. You'll Also Notice That I've Deliberately Left Out Cloud Services Like Azure, Aws, And Gcp In My Skill Profile. The Sheer Number Of Specific Services Available On These Platforms Makes A General Question About Mastering The Platforms Themselves Seem Rather Pointless. If You (Or Your End Customer) Specify Which Services Need To Be Handled Or Used By Me In The Scope Of The Project, I Can Certainly Give You A Meaningful Answer To That Question.
Please Also Note That, For Clarity, I've Chosen Not To List Every Possible Microframework And Programming Library Here. You Can Assume I'm Well Familiar With The Common Libraries For Data Handling And Querying (Redux, Zustand, Mobx, React-query, Backbone.js, Zod, Pydantic, Mongoose, Sqlalchemy, Entityframework, Etc.) When The Relevant Framework Or Language Appears In The List Below.
