About A

15 years transforming data into decision-making leverage for organizations.

I am a Data Manager & Data Architect, specializing in demanding banking and financial environments. I intervene when an organization wants to move from data that is endured to data that is mastered: reliable, governed, and truly useful to the business.

My areas of intervention:
🏗️ Data Platform & Architecture — Design and implementation of end-to-end data platforms: definition of target architecture, technology choices, implementation and industrialization. Experience with Data Warehouse, Data Hubs, Datalake, Lakehouse architectures, ingestion pipelines, and Bronze/Silver/Gold layers. Migration from legacy systems to modern platforms, with particular attention to quality, traceability, and governance from ingestion.

🚀 Delivery & Management — Steering data roadmaps, coordinating Run/Build teams, maturity audits, scoping and delivery of complex projects in a multi-BU environment.

🏛️ Governance & Compliance — BCBS 239, GDPR compliance, data catalog deployment, data ownership, Data Quality, and Data lineage.

What sets me apart: My intervention always starts from the value expected by the business and clients — not from the technology. I build end-to-end data value chains, from source to decision, ensuring each component serves a concrete use case. Technology-agnostic, I choose tools based on context, constraints, and objectives — not the other way around. My role is to align technical teams, business stakeholders, and management around a common, actionable, and sustainable data vision.
