Summary

I build systems where others just sell tools. AI isn't a buzzword for me but a lever to create real relief.

As an AI Solution Architect, I combine deep technical expertise with entrepreneurial thinking. I think in structures, not interfaces. I don't build demo projects but scalable architectures – robust, maintainable, effective.

My goal: empower companies not just to use AI but to lead with it. Not to experiment, but to take responsibility.
