Monthly warehouse spend cut 44%

The platform was paying for warehouse time it was not converting into useful latency. Cost looked fixed because nobody had query-level visibility tied to product workloads.

I traced where spend and latency actually came from, down to workload patterns and table design. The fix list focused on the highest-impact changes first, then sequencing.

Headline outcome: monthly warehouse spend cut 44% while keeping 5TB+ queried sub-second, with 20GB/day telemetry and 1M+ monthly ingests in production.
