Who I Am

About Me

I'm a Network & Systems Administrator with 5+ years of experience supporting enterprise and cloud-based infrastructure across AWS, GCP, and OCI.

My background spans firewall administration, VPNs, network security, and identity management — with hands-on experience in FortiGate, Cisco ASA, Meraki, and OneLogin. I've led firewall migrations, designed ZTNA environments, and built automation pipelines that keep deployments consistent and auditable.

I thrive in fast-paced distributed environments with 24/7 on-call responsibilities — comfortable working with both technical teams and business stakeholders to keep infrastructure secure and reliable.

"Automation-first. If I do it twice, I write a script. If a team does it twice, I build a pipeline."
