Seven years building test and release discipline into teams that had none. I care less about tool choice than about whether a regression can ever reach production twice.
Cut checkout-related production incidents from 6/quarter to 0 in two quarters.
Replaced a flaky, hand-run test checklist with an automated suite covering every payment path, plus a release gate that blocks deploy on failure.
Rebuilt the on-call rotation and runbook set after a string of 3 a.m. pages with no clear owner.
Introduced tiered escalation, a living runbook per alert type, and a blameless review cadence. Mean time to acknowledge dropped from 24 minutes to 4.
Added a contract-testing layer that catches breaking API changes before they ship.
Every service now runs consumer-driven contract tests in CI; three breaking changes caught pre-release in the first month alone.
Building a repeatable load-test harness ahead of a major traffic event.
Rolling out gradually across services; two of six migrated so far.
Own test strategy and release gating for a 30-engineer product org.
Built the company's first automated regression suite; trained three junior QA hires.
Manual test coverage for the publishing platform's editorial tools.
