Case Studies

What the work looks like.

Anonymized writeups of engagements where the engineering details matter -- what we built, how we built it, and what we learned.

Network Engineering

Cat9K install-mode upgrade across a 13-switch OT fleet

Building an Ansible install-mode playbook with 6-hour auto-abort rollback, the install_commit invoke_shell workaround, and a separate inactive-image cleanup pass.

DevOps & Automation

NetBox source-of-truth enrichment from 5 systems

Three CI repos (sw-to-netbox / tenable-to-netbox / splunk-to-netbox) bring SolarWinds, Tenable, Splunk, vCenter, and Cisco Secure Endpoint into a MAC-keyed asset record -- 860 nodes synced.

Cybersecurity

54-switch SNMPv3 fleet conversion across mixed firmware

SHA1+AES128 on FortiSwitch v6.2 and Cisco IPBASE images. SHA256+AES256 on FortiOS 7.x. One credential mapping policy. Zero polling outages.

Compliance & Governance

NERC CIP-005 evidence pipeline as a weekly GitLab CI job

FortiGate policy backups committed to self-hosted GitLab, auto-archived to the NCN CIP share. Audit prep becomes a query, not a project.
