What I'm looking for

I am seeking roles that blend customer-facing support, technical troubleshooting, and cybersecurity responsibilities in a collaborative, process-oriented team focused on continuous improvement.

I am an experienced customer service and operations professional with a strong background in cybersecurity, technical support, and high-volume client-facing roles. I bring a proven record of delivering reliable service and executing complex operational tasks across multiple industries.

Over my career I have managed large-scale delivery operations, supported internal technical systems, and provided frontline and escalation support in inbound/outbound call centers. I have executed thousands of deliveries and helped streamline workflows through SOP creation and process improvements.

I hold cybersecurity training including CompTIA Security+ coursework and a Google Cybersecurity certificate, and I have hands-on experience with SIEMs, Kali Linux, Python, and web technologies. I have also developed training programs, intranet sites, and technical documentation to improve team performance.

I am driven to take on new challenges, rapidly learn new technologies, and contribute to teams that value operational excellence, security-minded practices, and strong customer outcomes.
