About
Operations discipline applied to infrastructure engineering
I bring nearly 20 years of customer-facing and operations experience from banking, financial services, airline services, and business operations. I now apply that same discipline to IT support, network administration, Linux systems, and cybersecurity.
My homelab functions as a production-style learning environment where I design architectures, deploy services, document changes, investigate incidents, validate backups, and improve reliability over time.

Case studies
Real infrastructure work, documented end to end
Multi-VLAN network segmentation
Designed an Omada-based network separating management, servers, workstations, IoT, media, printers, and guest traffic.
Outcome: Least-privilege access while preserving DNS, printing, mDNS, and automation workflows.
Read case study →Layered DNS architecture
Implemented Technitium DNS as the primary LAN resolver, with AdGuard Home providing filtering and encrypted upstream resolution.
Outcome: Centralized internal zones, consistent service discovery, and network-wide filtering.
Read case study →Vaultwarden recovery and hardening
Recovered a missing container, verified persistent data, checked SQLite integrity, recreated the service, and hardened the admin token.
Outcome: Restored service with verified backups, HTTP readiness checks, TLS validation, and secure credentials.
Read case study →Monitoring and observability
Combined LibreNMS, Prometheus, Grafana, cAdvisor, Node Exporter, Blackbox Exporter, and Uptime Kuma.
Outcome: Layered visibility into hosts, containers, network devices, service health, and uptime.

Let's discuss infrastructure, support, or network operations.
I am interested in IT support, network support, NOC, junior systems administration, and infrastructure support opportunities.
