What I'm looking for

I’m looking for a role where I can design and operate secure, high-performance network architectures—leading firewall/VPN/IDS-IPS, SIEM monitoring, and vulnerability remediation—to improve reliability, protect critical systems, and ensure compliance.

I’m a highly experienced Network and Security professional, focused on designing, implementing, and maintaining secure and high-performance network infrastructures. My background spans roles from Senior Network Security Consultant and Senior Network Security Engineer to Network Engineer, Network Support Engineer, and Network Administrator. I bring strong problem-solving abilities and a commitment to improving network reliability, protecting critical systems, and supporting organizational IT operations.

I handle multi-cloud network security architecture and bring expertise in cryptography & PKI, firewall engineering & operations, and vulnerability assessment & remediation. I’ve configured and managed vendor firewalls, and delivered secure network operations through advanced firewall policies, segmentation strategies, and encryption. I also strengthen defenses with Intrusion Detection & Prevention Systems (IDS/IPS), conducting security assessments, penetration testing, and threat analysis to reduce risk and improve resilience.

Operationally, I monitor security events using SIEM tools (including Q-Radar) and perform incident response to contain and remediate security breaches. I regularly support LAN/WAN configuration, Router & Switch Configuration, TCP/IP networking, and network monitoring & troubleshooting to minimize downtime. Alongside that, I support system & network hardening, access control management, and backup & disaster recovery, while maintaining cybersecurity compliance through technical documentation and best-practice recommendations.
