About Sébastien

Salesforce Architect with 14 years of experience in enterprise delivery. My domain: complex programs where data, AI, and business processes must work together.

Direct clients and consulting firms engage me for three types of missions:

1. Agentforce and AI Architecture
Design intelligent agents that work in production. Most Agentforce projects fail not because of the technology, but because the data architecture is not in place. I build this foundation.

2. Data Cloud and Multi-Cloud Architecture
Unify Sales Cloud, Service Cloud, Marketing Cloud, and Commerce Cloud around a single customer view. I designed the Data Cloud architecture for a leader with over 3,000 touchpoints across 30 countries.

3. Salesforce Implementation Audit and Recovery
30% to 70% of Salesforce projects miss their objectives. I diagnose what went wrong, restructure the architecture, and deliver an executable recovery plan in 90 days. No endless discovery workshops. Diagnosis, architecture, execution.

What I've delivered:
- Data Cloud, Marketing Cloud, Service Cloud Architecture: Global program (30 countries)
- CRM and multi-cloud integration architecture
- Enterprise Salesforce Architecture
- CRM and integration delivery
- 10+ enterprise programs in international consulting firms

I work on a long-term basis or on fixed-scope missions (audit, architecture, recovery).
