Summary

AI is my passion. It enables faster workflows, higher throughput, and greater efficiency. But for it to really work, processes need to be well thought out and adapted.

For over three decades, I have analyzed and improved business and IT architectures. Along the way, I learned how hard it can be to bring many individual parts together into a coherent whole.

I help you structure your processes, reduce complexity, and make the most of AI’s benefits. This creates clarity and stability for sustainable growth.
