What I'm looking for

I'm looking to contribute my cybersecurity, networking, SCADA, and IT/OT security background to a forward-thinking, security-focused organization safeguarding critical infrastructure while continuing to grow in cybersecurity.

I've delivered cybersecurity and IT/OT infrastructure projects for Hitachi Energy and Vestas Wind Technology across renewable energy environments. I secure SCADA systems, industrial networks, and enterprise-to-OT data exchange supporting reliable wind, solar, and HVDC operations.

I conduct vulnerability assessments, OT risk assessments, architecture reviews, asset discovery, network segmentation assessments, and security hardening. My work applies IEC 62443, NIST CSF, ISO 27001, and CIS benchmarks to strengthen security and compliance across SCADA, PLC, and industrial control environments.

I've also supported virtualization, backup, disaster recovery, incident response, Active Directory, FortiGate firewalls, VPNs, and industrial protocols including Modbus, OPC/UA, TCP/IP, IEC 104, and DNP3.
