• Executing and maintaining E2E, regression, and functional tests across multiple customer scenarios and configurations.
• Debugging cross-system communication by analyzing logs, payloads, and service interactions to identify root causes quickly and accurately.
• Using monitoring tools such as Datadog to validate system performance, trace flows, and detect inconsistencies or failures after releases.

• Strong experience testing complex FE and BE integrations (web apps, microservices, external systems)
