Freelancer profile translated to English.

Description

Specialist in Identity & Access Management (IAM), I ensure the security and governance of identities and access, at the heart of current cybersecurity challenges.

With experience in complex environments, I am involved in the entire identity lifecycle: entitlement management, implementation of security policies (RBAC, least privilege), application integration, and deployment of IAM solutions such as SailPoint IdentityIQ, Microsoft Entra ID, or Okta.

I have also contributed to structuring projects, including ISO 27001 audits, Active Directory to Entra ID migrations, and the implementation of security measures (SSO, MFA, flow monitoring, alerting). In parallel, I ensure operational maintenance, incident resolution, and continuous improvement of IAM processes.

Recognized for my rigor and ability to collaborate with business teams, I am committed to proposing secure, compliant, and operationally adapted solutions.

🔐 Areas of Expertise: IAM, IGA, SailPoint, Entra ID, Active Directory, SSO, MFA, RBAC

⚙️ Environments: Windows Server, Azure, ITSM tools (JIRA, Freshdesk)

📈 Objective: strengthen access security while facilitating user experience
