I build and secure enterprise and industrial networks across multi-site, cloud, and OT environments.

I've spent 25+ years designing, securing, and managing enterprise and industrial network infrastructure, from multi-site WANs and data centers to SCADA and OT environments.

At Industrial Network Solutions, I led engineering teams through the design, deployment, and commissioning of industrial infrastructure, managing two projects exceeding $1M and supporting technical proposals and pre-sales work.

At Deutsche Windtechnik and Delek Refining, I strengthened SCADA, refinery, cloud, and remote-access environments using NIST 800-82, the Purdue Model, Azure integration, SD-WAN, segmentation, and Cisco and Palo Alto security platforms.

I've also architected BGP and MPLS networks, led major fiber and WAN migrations, mentored engineers, and built practical documentation and automation to help teams operate securely.
