About

Professional summary

I am a senior IT and digital transformation leader with nearly 30 years of international experience in enterprise architecture, information architecture, data strategy, governance, and platform modernization. I align business priorities with practical technology execution across complex global organizations.

I have led enterprise-wide transformation, data management, analytics, cloud migration, and M&A integration programs for organizations including GSK, Microsoft, Nokia, IKEA, Swiss Re, Oracle, and MOLE Pharmaceutical Group. My work combines strategic leadership, architecture governance, solution design, and delivery management.

I specialize in data and AI architecture, including Data Mesh, Data Fabric, knowledge graphs, generative AI, LLMs, agentic systems, RAG, semantic models, and governed AI workflows. I build scalable approaches that connect enterprise data, processes, technology platforms, and business outcomes.

I have delivered measurable value through large-scale transformation programs, including €15M NPV savings from FP&A application consolidation, €100M inventory-cost reduction through data-provider optimization, and substantial infrastructure cost reductions. I also delivered a global EPM platform operating across 120 countries.

As a co-founder and COO, I bring an entrepreneurial and commercially minded perspective to technology investment, organizational design, and operational growth. I enjoy advising leaders, coaching architecture and governance teams, and translating complex requirements into actionable roadmaps.

I am committed to continuous learning and apply a pragmatic, analytical approach to digital transformation. I work effectively across business, technology, data, and governance stakeholders to establish sustainable capabilities and deliver lasting change.
