Outcome
9 — CoE members

Situation

A multi-cloud Salesforce estate across Europe and Africa needed a named CoE, not another round of vendor slides. It got one: 8M+ customer records governed, 99.9% availability.

I founded and led the nine-person CoE and owned the governance model.

Challenge

The operating model had to coordinate data flows between Salesforce, ETL layers, and Azure while maintaining availability.

Action

Sébastien created and led a nine-person Center of Excellence and designed the IT governance architecture for the estate.

Result

The solution governed 8M+ customer records and achieved 99.9% system availability.

Reflection

The verified proof is the CoE, record scale, multi-cloud governance, and availability; undocumented org counts, code volumes, or deployment gains are excluded.
