• Analyse logs and debug issues using DevTools (Network, Console, Application, cookies, localStorage)
• Collaborate closely with frontend and backend teams
• Ensure coverage of critical user flows (login, orders, financial operations)
• Build and maintain end-to-end (e2e) tests using Playwright or Cypress
