Indianapolis
02.2025 - Current
- Designed FortiGate architectures for multi-site clients, including segmented VLAN topologies,
inter-site routing, SD-WAN failover logic, and Azure IPsec integration, improving performance and
resiliency.
• Built Azure hybrid networks (VNets, NSGs, UDRs, routing tables, VPN gateways), enabling secure
cloud connectivity and identity integration.
• Conducted technical discovery sessions, translating business requirements into technical
specifications and implementation-ready documentation.
High-Impact Accomplishments
• Detected an active brute-force attack against a client’s VPN portal by identifying abnormal login
behavior in real time. Prevented compromise by redesigning the authentication path, implementing
SAML with MFA, and fully eliminating password-based VPN access.
• Engineered a PowerShell-driven SharePoint archive migration solution handling more than one
million files. Automated batching, throttling, error handling, metadata retention, and dependency
checks, reducing a multi-month manual effort into a controlled, repeatable process.
• Resolved a persistent RDS performance outage overlooked by multiple engineers by analyzing TCP
retransmission patterns and modifying low-level Windows networking parameters. This eliminated session drops and restored stable performance despite limited bandwidth.
• Diagnosed enterprise-wide WebView2 failures caused by Windows 10 to 11 upgrade artifacts.
Reverse-engineered the registry state, identified stale environment variables, and built a remediation
process to repair runtimes without reinstallations.
Additional Responsibilities
• Acted as senior escalation for firewall, routing, Azure, identity, and performance incidents.
• Authored runbooks, troubleshooting guides, and standardized deployment procedures.
• Provided mentorship to junior engineers on network design, scripting, and cloud fundamentals.
• Delivered detailed incident reports and architectural recommendations to executives and technical
teams
