Portfolio / Resume

I build resilient infrastructure across multi-site networks, remote access, and datacenter environments.

Network engineer with 12+ years across enterprise WANs, secure remote access, and datacenter environments. I focus on the work that has real stakes: migrations, network modernization, and the engineering that keeps firm operations running.

Professional Summary

I bring hands-on depth to infrastructure changes that need to land cleanly.

My background spans enterprise WANs, secure access, datacenter networking, and infrastructure support. The approach is consistent: understand the environment first, then execute changes that hold up in production.

About

How I approach the work

My focus is infrastructure changes that need to go right: network modernization, datacenter transitions, and the coordination across teams and vendors that prevents a cutover from becoming an incident.

Experienced across SD-WAN, datacenter migrations, and secure access — the work that moves infrastructure forward without disrupting operations.
Comfortable with after-hours changes, complex cutovers, and coordination across IT teams and vendors.
Deep background with NetScaler / ADC, Citrix-adjacent environments, and the operational details that make complex transitions succeed.
