Profile
Freelance SAP BTP expert with over 7 years of experience, from mid-sized companies to large enterprises, from intralogistics to retail. I combine architecture expertise with hands-on development: from integration strategy to full-stack development through to go-live. Using modern AI tools I develop faster and more precisely. I work in a structured way, communicate directly and deliver in short iterations.
