pulse
Ad tags fail silently. Pulse watches the measurement layer itself, across the site and the dealer network.
team one internal tool, deployed in production on the agency's internal aws/eks platform. vendor specifics withheld.
The origin story is the argument: dealer-site conversion tags once dropped off completely and nobody noticed for weeks, because monitoring meant a person scanning pivot tables. Pulse watches 2,246 tags across lexus.com and ~244 dealer sites with daily automated pulls, and Postgres accumulates history past the ad platform's hard 60-day lookback — the database remembers what the vendor won't.
The anomaly engine runs in three layers: deterministic rules, then statistical day-of-week baselines with adaptive per-tag thresholds, then a model-written narrative — the LLM explains, it never detects. Correlated-failure grouping turns fifty dealer tags dropping at once into one root-cause alert instead of fifty pages of noise.
Full case study in progress — artifacts pending clearance or writing time. The insight below is already earned.
Analytics fail silently — the measurement layer needs its own measurement. A broken tag looks exactly like a quiet day until you check.
