• Integrate tests into Azure Dev Ops pipelines so teams get fast actionable feedback and diagnose flaky or slow tests rather than normalizing them
• Use API contracts and tools such as Swagger and Postman to investigate behavior validate integrations and support test setup
• Investigate defects with engineers contribute to root-cause analysis and use findings to improve test coverage and prevent recurrence
• Improve test data environment use diagnostics and reporting so failures are reproducible and useful to developers
• Take responsibility for quality across application releases coordinate release testing ensure critical risks and defects are visible and provide a clear readiness recommendation based on evidence and agreed criteria
• Use Azure Dev Ops test plans or suites where they help coordinate coverage and provide traceability

• Significant hands-on QA experience testing complex applications and integrations
