🔒 Freelance Network & Security Architect with over 15 years of experience, I support large companies in the design, security, and optimization of their critical infrastructures.
💡 Specializing in F5 solutions (APM, LTM), firewalls (Fortinet, Palo Alto, Check Point), and secure remote access environments (Pulse Secure, Zscaler, Netskope), I am involved in:
• Complex migrations (end-of-life solutions → modern secure architectures)
• Automation of security deployments (Ansible, GitLab CI/CD, Rundeck)
• Regulatory compliance (ANSSI, LPM, NIS) and environment hardening
• Level 3 support and crisis management for critical incidents
✅ My interventions guarantee my clients:
service continuity, compliance with security standards, and upskilling of internal teams.
