Illustrative vibration signal with 3σ bounds · not real data

This is industry work described in general terms. Employer names, data, and screenshots are intentionally left out, and the chart above is illustrative.

01The problem

Maintenance was reactive. By the time a machine sounded wrong, the repair was already expensive and production had already stopped.

02What I built

  • Statistical control bounds (3-sigma) learned from each machine’s own normal vibration behavior
  • Queries on Azure Data Explorer (KQL) that scan high-frequency telemetry efficiently
  • Scheduled jobs that score new readings and surface out-of-bounds equipment

03The result

  • Maintenance teams see which machines are drifting, not just which ones already broke
  • Simple, explainable statistics that technicians can trust and verify
