Clinic Workflow Automation System

End-to-end BPMN-driven system for streamlining dental clinic operations. Automates appointment handling, treatment tracking, lab coordination, and billing using containerized services, event-driven architecture, and Kubernetes orchestration.

Features

• Modular BPMN Workflows: Developed Camunda-based workflows to automate patient processes and optimize resource management.
• Event-Based Process Integration: Kafka used for loosely coupled communication between clinic and lab workflows.
• CI/CD & Orchestration: Jenkins pipelines with AWS (ECR, EC2, EKS) and Kubernetes for scalable deployments.
• BPMN Workflow Engine: Camunda for transparent, model-driven execution and lifecycle management.
