      Preferred Candidate

      A strong candidate should be able to take a requirement from:

      Requirement → Database Design → API Design → Backend Implementation → Kafka/Event Processing → Frontend Integration → Docker → CI/CD → Kubernetes/EKS → Production Monitoring and independently own the feature through to production.

      Experience 4+ years of professional software development experience, with significant hands-on backend development experience in Java Spring Boot or Node.js.
