About

A pragmatic bridge between business and technology.

I’m an ERP Solution Architect with over seven years of experience in international Microsoft Dynamics 365 Finance & Operations and Power Platform projects. My focus is the design and delivery of solutions that are scalable, compliant and genuinely usable — not just on paper.

I act as the connector between business stakeholders, IT departments and delivery teams. Whether the engagement starts at presales, requirements engineering or hypercare, I bring a results-oriented, hands-on attitude grounded in a Master’s degree in Logistics & Supply Chain Management and certified Microsoft expertise.
