What I'm looking for

I seek a leadership role in infrastructure and security to design secure cloud/on‑prem environments, implement observability and PCI‑DSS compliance, lead teams, and reduce fraud within a collaborative, process-driven organization.

I am an IT infrastructure and cybersecurity professional with over 30 years’ experience designing, implementing and maintaining secure networks and cloud environments across financial services and consumer goods. I deploy observability and SIEM solutions (DataDog, Dynatrace, Wazuh, Splunk), manage AWS, Linux and Windows, and use shell scripting to automate operational tasks.

I led the creation of an Infrastructure and Security department, documented operations, and enforced PCI‑DSS compliance (AoC) to ensure business continuity. I have investigated fraud alerts, managed hybrid cloud and on‑prem environments, coordinated IT operations for startups and enterprises, and founded an infrastructure company that scaled to significant revenue and staff.
