Profile & Objective
Experienced systems and network administrator in managing heterogeneous environments (Windows, Linux, AS400, virtualization) and operational security of production infrastructures.
With daily practice in automation, monitoring, and N2/N3 incident management, I also develop a cybersecurity and AI-oriented homelab to experiment with secure architectures, threat detection, and incident response.
My goal is to directly join a Master 2 in Cybersecurity to consolidate the theoretical foundations and evolve towards security engineer, SOC, or secure architecture roles.
Technical Skills
Professional Experience
- Management of production infrastructure and cross-functional projects with internal teams and external providers in a highly constrained availability and security context.
- Administration of SMA Opcon scheduler to automate and centralize recurring processes on Windows, Linux, AS400, Informatica, EDI, and ODI environments, with industrialization of production reports.
- Production deployment of workflows, jobs, and batches (Informatica, ODI), support for development, data, and business teams during POCs and deployments.
- Writing and updating operational documentation (DAT, DEX, DIN, PMEP, MODOP) and contributing to continuous improvement of procedures.
- N2/N3 operations and production incident handling, production plan monitoring, and participation in critical operations planning.
- Systems administration (Windows, Windows Server, Unix), VMware/Hyper-V virtualization management, and backup/restore operations (Veeam, MIMIX).
- Network and telecom incident tracking, operator escalation, and site-to-site IPSEC VPN tunnel administration on FortiGate, as well as Cisco network infrastructure.
- Management of over 200 workstations in a contact center environment.
- Installation and configuration of physical and virtual servers for telephony and CRM operations.
- Asterisk administration supporting over 500 daily calls and integration of call center CRM solutions (VOX CRM, Goautodial, PhingooCRM).
- Network equipment maintenance (Wi-Fi, printers, copiers) and incident diagnosis.
- Design and deployment of cabling solutions (fiber optic and copper) for network infrastructures.
- WAN network interventions to optimize performance and reliability.
- Network malfunction diagnosis and resolution, cable routing improvements for better efficiency.
Projects & Cybersecurity Homelab
Setup of a homelab based on Proxmox VE (Lenovo ThinkCentre M920q) hosting multiple virtual machines and containers to simulate enterprise environments.
Deployment of a pfSense firewall (Zotac N100) with WAN/LAN separation, Suricata IDS, DNS filtering (pfBlockerNG), and dedicated Access Point to isolate the homelab from the ISP network.
Creation of isolated network segments to test incident response scenarios, segmentation, service hardening, and behavior analysis.
Integration of Zabbix for real-time monitoring, Docker for microservices architecture simulation, and Active Directory/DNS setup to experiment with security policies and authentication models.
Use of n8n to automate log processing and response orchestration (DIY SOAR approach), as well as AI/LLM tools for threat analysis, alert triage, and investigation assistance.
