I am a seasoned professional with 15+ years of hands-on experience designing, implementing, and securing large-scale mission-critical infrastructures. An expert in high-availability environments, I possess a deep technical command of advanced routing and switching (BGP, OSPF, SD-WAN) and enterprise-grade security protocols that exceed standard certification levels. Throughout my career within the UN system and private sector, I have specialized in diagnosing complex architectural failures and optimizing network performance for global operations, ensuring 99.9% uptime in high-pressure scenarios. My expertise extends to firewall management such as Fortinet, VPN orchestration, and load balancing, combining a solid foundational CCNA with the practical, high-level troubleshooting skills of a CCNP/CCIE professional. I am a strategic problem-solver committed to international security standards and the continuous evolution of secure communication networks.
