-   Validate settlements, fees, exchange rates, payouts, invoices, and reports, alongside wallet top-ups and deductions, vouchers, inventory, and item delivery to games and partners.
-   Use SQL, logs, API traces, and browser developer tools to investigate root causes, and test background jobs and scheduled tasks.
-   Build and maintain **Playwright** automated tests for critical journeys, API validation, and regression coverage.
-   Maintain test cases traceable to Jira, communicate risks and coverage gaps clearly, and contribute to improving the QA process.
