Back to original languageAbout Sébastien
I support companies in the architecture, operation and optimization of their databases, especially when performance, availability or reliability become critical.
My most frequent interventions:
- Diagnosis and resolution of production incidents
- Performance optimization (queries, indexes, data models)
- Implementation of backup, DRP and high availability strategies
- MySQL replication (master/slave, multi-master)
- SQL Server ↔ MySQL migrations
- Architecture audit and concrete recommendations
I worked for over 15 years at the heart of a company's information system, with a technical and business vision, including:
- SQL Server, MySQL
- ETL (SSIS, Talend)
- Multi-source data (CSV, Excel, JSON, MySQL…)
- Environments subject to GDPR constraints
I intervene both on long-term assignments and on targeted projects to solve specific problems.
