Freelancer profile translated to English.

Description

I intervene on IT infrastructures that are causing problems. I stabilize them, structure them, and make them evolve.

With 20 years of experience in critical environments (banking, watchmaking, large accounts), I have developed a rare dual expertise: technical mastery for diagnosis and resolution, and leadership skills for structuring and coordinating cross-functional teams.

My typical missions:

- Infrastructure Technical Project Manager: leading transformation projects, coordinating multi-teams (systems, network, DBA, application, business), DAT/DEX deliverables, go-live

- Operations Manager / MCO: structuring ITSM processes (ITIL v4 certified), service governance, SLAs, incident reduction, documentation

- Audit & Recovery Mission: rapid diagnosis of an unstable environment, identification of bottlenecks, reliability plan and implementation — I deliver measurable results

Some concrete results:

→ Incident reduction x4 on a critical Docker platform (Audemars Piguet)

→ GED migration on WAS9 without service interruption (BNP Paribas)

→ Structuring of the MCO model and selection of outsourcing partners for an international IS (Rexel)

Recent environments: Rexel, Audemars Piguet, BNP Paribas, HSBC, Euroclear

Stack: Linux · Docker · Tomcat/WAS/JBoss · Axway CFT · Ansible · Azure DevOps · ServiceNow · ITIL v4

Available quickly — Paris, Lyon, Geneva, remote.
