Infrastructure work — the real ones.

Diagrams, topology views, migration artifacts, and audit outputs from actual environments. Some are client deliverables (redacted where necessary); some are lab work that later became reusable templates.

OpenShift migration program.

Production and DR vCenter analysis (RVTools), UCS health audit across 68 blades, Jira-import CSV for modernization backlog, POC runbook targeting the C2-WebSphere-Cluster for Single Node OpenShift, OpenShift working session with Red Hat engineering. Findings surfaced expiring SSL certificates, multipath storage failures, dead boot LUNs, and a critically unhealthy UCS node — all of which shaped the migration wave plan.

Artifact

Infrastructure health reports

RVTools-derived reports covering both vCenter environments, host-level drill, storage paths, certificate expiries, boot-LUN status.

Artifact

Jira-import CSV

Structured backlog for the modernization program — every finding becomes a ticket with priority, workstream, and owner hints.

Artifact

POC runbook (SNO)

Single Node OpenShift POC on the C2-WebSphere-Cluster target — prerequisites, sequence, rollback posture.

Artifact

Migration wave plan

24–36 month horizon, workload-class banding, dependency sequencing.

Representative diagrams

Visualizing infrastructure stories

Selected diagrams from past engagements. Each illustrates how a real environment was structured and how services were connected across datacenters, clinics, and cloud providers. These visuals were originally delivered as client-ready artifacts and are reproduced here with proprietary details removed.

Network topologies

Meraki infrastructure examples

The following diagrams illustrate real-world network topologies using Cisco Meraki gear. These visuals have been recolored to align with the site’s dark theme while preserving their technical clarity.

Improved Meraki topology for Armadillo Hotel Group — Armadillo Hotel Group Meraki topology — hotel network layout across buildings with cloud-managed switches, access points, gateways and capacity planning for 1/3 building utilization.

Improved Meraki topology for Kendra Scott — Kendra Scott network overview — retail HQ and e‑commerce lane topology with core switching, distribution and cloud-managed Wi‑Fi for multi‑location operations.
