 * Design and implement Java-based microservices and APIs producing/consuming from Kafka topics
 * Develop full-stack features (backend + UI integration) supporting event-driven architectures
 * Re-architect/refactor producer/consumer applications for MSK compatibility (IAM auth, TLS, VPC connectivity, security groups)
 * Implement monitoring/alerting/observability using CloudWatch, Prometheus/Grafana, or equivalent
 * Define and execute data validation, dual-write/dual-read, and rollback strategies during cutover
 * Optimize Kafka topic partitioning, replication factor, retention policies, and consumer group configurations
 * Collaborate with DevOps/Infra teams on Terraform/CloudFormation-based MSK provisioning
 * Ensure compliance with security, encryption (at-rest/in-transit), and access control standards (IAM, SASL/SCRAM, mTLS)
