Skills · Knowledge Map

Every bar earned.
Nothing claimed.

Skills mapped to where they actually live — across the OSI stack, the delivery lifecycle, AI tooling, and customer success under pressure.

Most developers work at Layer 7; most sysadmins at Layers 1–4. Working across all seven — from imaging kiosk hardware to shipping Flutter apps — is rare.

Cases that prove the bars

Two recent customer-success signals. The full set — infra, hardware, mobile, AI, home lab, and own product — lives on Cases.

Guests at the gate

Large Australian university · housing & guest management

Off-hours P1: gates denying valid guests, two root causes, one customer voice.

Migrating trust, not just infra

Enterprise quality management · regulated customers

Only T3 on a high-ARR platform mid-migration: angry regulated customers, weak comms, UK eng bridge.
