Freelancer profile translated to English.

Description

For 17 years, I have been working on production SQL Servers. Today, I am Head of Database Administration at Shift Technology, a French insurtech unicorn, where I oversee the data architecture of a SaaS platform valued at over a billion dollars.

What I do concretely: I enter a SQL Server environment, find what is expensive, and fix it.

Queries that consume 110 seconds of CPU with each execution. Default configurations that saturate RAM in production. Missing indexes on tables with 50 million rows. These problems exist in almost all the environments I have audited, and they go unnoticed because classic monitoring tools alert on thresholds, not on context.

I intervene in three types of missions:

Performance Audit: Complete diagnosis of your SQL Server, prioritized report, actionable recommendations. Results in 48 to 72 hours.

Targeted Optimization: Slow queries, contention, indexing issues, server configuration. I intervene on the specific problem that costs the most.

Architecture & Support: Data pipeline design, migration, scalability, high availability.

My clients are tech teams in B2B SaaS, healthtech, fintech, and logistics who need an expert external perspective without hiring a full-time senior DBA.

Published author on SQLShack. Founder of AutoDBA, an AI-powered SQL Server diagnostic tool.
