• Integrate backend services with WSO2, IAM, Vault/PKI, API gateways, workflow engines, message brokers and external systems.
• Build resilient asynchronous processing using retries, timeouts, idempotency, dead-letter queues and correlation IDs.
• Guide relational data design, transactions, migrations, versioning, consistency and traceability.
• Own Kubernetes application concerns, including deployment configuration, health checks, scaling, observability and troubleshooting.
• Define unit, integration, contract, component, end-to-end and security testing practices.
