Worked on the aws-greengrass/aws-greengrass-nucleus repository to deliver a robust endpoint-switch deployment capability for IoT systems, focusing on safe remote configuration changes and reliability. Developed features in Java that included pre-flight connectivity checks using a standalone MQTT connection utility with retries and exponential backoff, ensuring deployments only proceed when connections are validated. Enhanced error handling by introducing targeted error codes for deployment failures, improving diagnostics and recovery. Strengthened deployment logic with rollback metadata persistence and config snapshots to reduce risk. Emphasized quality through comprehensive unit and end-to-end testing, leveraging Java and MQTT protocol expertise to improve backend reliability and maintainability.
