Monitoring & Testing

Why this matters: Observability and tests catch regressions early, reduce MTTR, and enable confident, frequent releases. We ship with confidence by instrumenting apps end-to-end: unit and integration tests, accessibility checks, and production observability. Our approach emphasizes fast feedback loops, clear failure signals, and actionable telemetry. Preferred defaults: Sentry for errors/perf, Playwright for E2E, Vitest or Bun Test for unit, OpenTelemetry for tracing, Lighthouse CI for budgets.
