As a self-entrepreneur through YSN Production, I designed and developed a complete multiplayer game in C#, with a security-oriented approach: encryption of local user data, secure hashing of keys, and implementation of a two-factor authentication (2FA) system for logins and registrations. I deployed a database server on Microsoft Azure PlayFab and configured a multiplayer server using Photon Network, applying best practices for securing communications and managing credentials. I managed the entire project, from design to the game's release on Steam.

At OGF, I was responsible for deploying and administering the SentinelOne EDR solution across all company workstations and servers, over 6,000 devices. I participated in project management from start to finish, from the gradual deployment phase to generalization across the entire fleet, in coordination with the CISO and the infrastructure team. I ensured continuous monitoring of agents, tracking their successful enrollment, managing offline machines, and analyzing and qualifying security alerts reported by the console.

I also handled the MCO (Maintenance in Operational Condition) and MCS (Maintenance in a Secure State) of the solution, ensuring the operational functioning of the EDR, processing security incidents, managing quarantines, exceptions, and false positives, as well as adjusting protection policies according to business needs. I contributed to the production and updating of security KPIs, to ensure clear monitoring of the fleet's status, alert volume, resolution rate, and remediation actions.

In parallel, I participated in setting up a global infrastructure monitoring solution via Site24x7 to enhance service availability and anomaly detection. I also contributed to the migration from Office 2013 to Office 365, workstation management via Intune/SCCM, configuration hardening, and the application of security policies adapted to user and server environments. Finally, I was involved in incident management via ticketing, case tracking, and incident response in a complex production environment.

At ADP, I was responsible for configuring and setting up StormShield routers, switches, and firewalls, as well as securing and maintaining in operational condition (MCO) an industrial automation supervision network. I implemented network security strategies (segmentation, risk analysis, access management, workstation hardening) as part of 2 security audits. I managed vulnerability management, patch application, and the implementation of remediation plans. I ensured compliance with LPM regulations, performed detailed network mapping, and produced comprehensive documentation, procedures, and technical diagrams. I also developed programs in Scada Basic for PcVue to ensure the proper functioning and reliability of supervision applications.
