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 tailored.

For over three decades, I've analyzed and improved business and IT architectures. In the process, I've learned how hard it can be to create a cohesive whole from many parts.

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