Independent Senior IT Architect

IT architecture that connects strategy with delivery.

I design and deliver complex IT solutions — from enterprise and solution architecture to Microsoft Azure, cloud transformation, and software engineering. My approach combines strategic architecture responsibility with hands-on technical implementation.
