Cards are lab proof + transferable themes, not six polished product demos. Titles track CV LAB PROOF and work themes. Write-ups follow the docs standard.
NetBox as source of truth (work + lab)
Deploy and upkeep of NetBox for IPAM/DCIM — inventory hygiene so addressing, device roles, and change history stay one place instead of spreadsheets. Same tool at work and in the lab. Companion lab/demo: a minimal custom-script stub for reports / small plugins — not employer metrics.

Git hooks + CI-style gates (lab / demo)
Scrubbed hook samples for quality gates before a path is trusted (secret-shaped string rejects, docs checks). Framed as a lab/demo public mirror — not a CV employment deliverable.

Observability catch story (lab-framed / transferable)
Grafana, Prometheus, and Zabbix for host and network visibility. One lab write-up shows how a missing metric panel + alert path caught a guest disk-fill before it became a surprise outage — no employer data.

Lab incident write-up
EVPN / VXLAN lab diagrams (lab only)
Virtualized Arista VxLAN fabric for switching tests on owned lab gear. Diagrams and practice notes only — not claimed as production EVPN expertise. No underlay addressing published.

AI / homelab sandbox (lab)
GPU host deploy and dedicated GPU guests for local LLM inference on owned hardware. Isolation and resource limits stay in the lab — no private addressing published here. NVIDIA AI certification path in progress (not complete).

Homelab platform (Proxmox · Ceph · backup)
Multi-node Proxmox VE with corosync and an external QDevice; Ceph hyperconverged RBD for guest disks; TrueNAS SCALE storage; Proxmox Backup Server for scheduled backups.

Lab switching (Arista · Juniper EX)
Arista switching (also a work focus) plus lab Juniper EX. VLAN / multi-plane segmentation for hypervisor, storage, and BMC planes in lab.
Tags: Arista · Juniper EX · Lab
Identity & security lab
FreeIPA for Kerberos/LDAP and host enrollment; Keycloak SSO federated from IPA LDAP over OIDC. Wazuh SIEM and Greenbone vulnerability scanning in the same lab footprint.

Ansible role skeleton (lab / skills sample)
Minimal Ansible role layout for lab practice — carefully marked lab/skills, not production orchestration expertise. Companion public sample.
