Designed HIPAA-compliant Java/Jakarta microservices for healthcare payer platforms with PHI encryption and audit logging. Built RESTful and SOAP APIs for eligibility, claims, and provider workflows following HL7/X12 EDI standards. Implemented Apache Camel pipelines (EIP patterns) for routing, transformation, and orchestration across payer systems. Built Camel routes with JMS, Direct, File, HTTP, and SQL components, centralizing integration logic. Designed Camel processors for HL7-to-JSON transformation and healthcare transaction normalization. Implemented ActiveMQ durable queues for async, high-volume transactions with retry and dead-letter policies. Led Spring Boot microservices using Java 11 with Kafka event ingestion and Avro Schema Registry. Built HIPAA-eligible AWS architecture (EC2, S3, RDS, IAM) with VPC segmentation and Multi-AZ failover. Implemented Kafka producers/consumers for real-time claims and eligibility with exactly-once semantics. Deployed microservices on OpenShift and AWS EKS using Helm, HPA, and RBAC network policies. Built CI/CD pipelines with Jenkins, Docker, and Artifactory with SonarQube quality gates. Managed IBM Cloud deployments (IKS, IAM, Secrets Manager) in HIPAA-regulated environments. Optimized MySQL schemas with composite indexes and table partitioning for claims performance. Configured CloudWatch dashboards and structured logging for AWS production observability. Implemented OAuth2/JWT with Spring Security RBAC and audit logging for HIPAA compliance. Built JUnit 5/Mockito test suites with TDD and CI-enforced coverage thresholds. Mentored junior developers and led code reviews enforcing microservices best practices. Collaborated with product owners delivering sprint demos and POCs in Agile/Scrum via Jira.
