What I'm looking for

I seek a hands-on network/security role where I can design secure, scalable cloud and enterprise networks, lead improvements, work in a collaborative security-first culture, and advance into broader security leadership.

I am a dedicated Network Security Administrator with seven years of experience designing, implementing, maintaining, and supporting secure network infrastructures. I hold CCNA, CEH, NSE4, NSE7 and multiple security certifications, and I specialize in cloud networking (AWS, Azure, GCP), firewall platforms, and network performance optimization.

As a Network and Security Unit Supervisor since 2017, I have led network design, vulnerability assessments, SOP development, and on-call security operations, earning two Letters of Appreciation. I focus on practical, compliant security measures, clear visualization reporting, and collaborating with teams to align network security with business objectives.
