• Integrate healthcare devices and ensure secure, real-time data synchronization.
• Optimize performance, scalability, and reliability in a medical-grade environment.
• Manage CI/CD pipelines (GitLab CI) and deployments on AWS (ECS, S3, SQS, KMS).
• Monitor production systems (Prometheus, Grafana, Datadog).
• Collaborate with doctors, nurses, and remote developers to translate medical workflows into robust software.
• Ensure strict GDPR compliance and security best practices.
