5. QA Strategy & Leadership:

- Define and implement QA strategies for payment applications and microservices.

- Establish automation-first testing practices and identify opportunities for test automation.

- Define testing approaches for functional, integration, regression, API, performance, and end-to-end testing.

- Establish automation standards, coding guidelines, and framework best practices.

- Review test plans, test cases, automation scripts, and execution results.

- Mentor QA engineers and drive continuous improvements in testing quality.

6. CI/CD & Continuous Testing:

- Integrate automated test suites into CI/CD pipelines.

- Configure automated test execution within build and release workflows.
