• Build integrations with payers, HIEs, QHINs, and healthcare partners using REST APIs, FHIR R4, HL7/ADT, C-CDA, SFTP, and file‑based interfaces.
• Implement data validation, patient matching, reconciliation, provenance, duplicate handling, and exception workflows.
• Build and operate AWS services including ECS/Fargate, Aurora PostgreSQL, S3, SQS, EventBridge, CloudWatch, IAM, KMS, and Secrets Manager.
• Strengthen CI/CD, automated testing, environment separation, deployment, rollback, monitoring, backup, and recovery.
• Implement HIPAA‑appropriate security, role‑based access, PHI protection, audit logging, and secrets management.
