• Verify end-to-end transactional flows across frontend, mobile, backend, database, and third-party systems.
• Perform ad hoc, exploratory, negative, boundary-value, and edge-case testing.
• Validate transaction status, payment results, inventory changes, refunds, cancellations, and reconciliation data.
• Conduct regression testing before product releases and major events.
• Collaborate with the SRE team on performance and load testing before high-traffic on-sale periods.

3. Defect Management and Quality Reporting

• Document defects clearly with reproducible steps, supporting evidence, expected results, actual results, severity, and priority.
• Track defects throughout their lifecycle and ensure that issues are properly resolved and verified.
• Collaborate with Product Owners, Backend Engineers, Frontend and Mobile Engineers, and SRE/DevOps Engineers to investigate issues and identify root causes.
• Verify bug fixes and assess their potential impact on related product areas.
• Prepare test execution reports, defect reports, and release-quality assessments.
• Communicate product-quality risks and release concerns clearly to relevant stakeholders.
• Support internal teams in investigating product incidents and production issues.

4. Test Automation and Process Improvement

• Gradually develop automated tests for APIs and critical transactional workflows.
• Maintain and improve automated regression test suites.
• Integrate automated tests into the CI pipeline where appropriate.
• Use tools such as Playwright, Cypress, pytest, k6, JMeter, or equivalent testing solutions.
• Support performance, load, and basic security testing activities.
