API and integration testing

- Validate authentication, user states, data persistence and asynchronous workflows
- Build and maintain regression suites for critical product journeys
- Identify race conditions, edge cases and failures beyond standard happy-path scenarios
- Perform exploratory/manual testing for new features and scenarios where automation isn't appropriate
