A Day in the Life
Your morning starts with reviewing new pull requests and checking overnight CI results. You spend a focused block writing Playwright E2E tests for a feature that ships next week. After lunch, you investigate a flaky test, triage bugs from the bug tracker, and pair with a developer to add better error handling that makes a feature more testable.
