How I work

  1. 01

    Isolate

    Find the layer the fault lives in before touching anything: cable, route, port, certificate, config.

  2. 02

    Fix

    Fix it there, not three layers up where the symptom showed.

  3. 03

    Script

    Turn the fix into automation so the same ticket never needs a human twice.

Clear the bricks and catch the falling pickups. Move the mouse (or drag) to steer.
