  • Verify cross‑browser and cross‑device behavior for responsive web apps and native Android and iOS applications
  • Validate analytics events and user journeys end‑to‑end
  • Log high‑quality defects with clear reproduction steps, impact, and evidence (screenshots, videos, console/network traces)
