Living Lab Atlas
Infrastructure Lab
This is Mark's self-hosted homelab running entirely on consumer hardware, built and operated on his own personal time to master complex systems in practice. Across four dedicated physical nodes, he has implemented complex multi-VLAN network segmentation (8 segmented VLANs), locked-down firewall controls with zero open inbound ports, centralized SSO with hardware MFA, local AI inference clusters, and a custom 4-season outdoor computer vision security system.
Every metric on this page reflects real-world engineering and deterministic infrastructure cartography backed by a NetBox single source of truth. Retired systems, such as the multimodal VLM intent engine, are documented alongside live production workloads, demonstrating pragmatic engineering judgment and operational discipline.
OT Context Engine: Local RAG Pipeline & Sanitizer
Mark's Apple M4 Pro node hosts a specialized RAG engine comparing Purdue Model operational technology context pipelines. Explore the live mirrored interface with benchmark analytics, sanitization filters, and build logs.

Unraid Primary Storage & Application Host
Hosts the primary storage array and the bulk of the self-hosted application estate, including the identity provider, the NetBox source of truth, and the reverse proxy tier.

10G SFP+ backbone, VLAN 2 (Servers)
Mirrors the primary uplink at the hardware ASIC level to the Security Onion sensor, so packet capture adds no forwarding load.
Carries tagged segments from the core to endpoints. Management interfaces live on VLAN 1.
AP management interfaces sit on VLAN 1 (Management & LAN).
