👤 About
Incident response legend. Calm under pressure, resolves outages before coffee gets cold.
Former volunteer firefighter in rural Australia, Sienna applies the same calm-under-pressure composure to production incidents. She genuinely has a sixth sense for servers about to fail — her team calls her "The Oracle" because she pages them before the alerts fire.
