Your Mission

Automate API test coverage and test REST and gRPC endpoints with Postman, grpcurl, or similar.
Verify event-driven flows across message queues such as Kafka, RabbitMQ, or NATS, including retries and duplicate handling.
Run regression testing after every deployment, manually where automation does not yet reach.
Log, track, and manage defects in Jira with clear reproduction steps, payloads, and service logs.
Validate data across services with SQL queries where a check calls for it.
