What I'm looking for

I seek a collaborative role focused on firewall and network security, automation of repetitive tasks, opportunities for continuous learning, and meaningful impact on infrastructure security.

I am a cybersecurity professional with hands-on experience in firewall administration and network security, with a strong background in Fortinet and Cisco technologies.

I administer and support Fortinet security devices including FortiGate, FortiAnalyzer, and FortiWeb, and manage large-scale deployments via FortiManager while monitoring events for threat detection and compliance reporting.

I troubleshoot critical incidents, deploy site-to-site and remote VPNs, contribute to infrastructure migration projects, and prepare technical documentation such as network diagrams, RCAs, and configuration manuals.

I value collaborative teams, proactive problem-solving, automation through scripting (Python, C++), and continuous learning, supported by certifications and specialized training in network security.
