What I'm looking for

I'm looking to lead AI, data, and cloud transformation where I can align boards, product, and engineering around measurable value, responsible governance, and scalable delivery.

I lead AI, data, and cloud transformation engagements through Nerisia and Atreus, translating executive strategy into governed platforms, product roadmaps, and measurable business outcomes.

At Google, I led a €100M+ AI and analytics portfolio across EMEA, standardized Vertex AI, BigQuery, and Looker architectures, and helped cut time to production by 35%. I also built AI offerings that improved customer-support handling time by 23%, increased defect-detection precision to 94%, and scaled analytics reference architectures across 12 markets.

Previously at Telefónica, I built an AWS-native analytics platform adopted by 90% of business units, improving delivery speed by 40% and reducing IT costs by 18%. My work spans privacy-ready data lakes, MLOps, IoT, digital twins, GenAI controls, and value dashboards that connect technical delivery to ROI.

I build high-performing teams, operating models, and partner ecosystems around responsible AI, security-by-design, and clear accountability. Across public sector, finance, telecom, automotive, retail, and manufacturing, I focus on making ambitious technology programs useful, compliant, and scalable.
