Overview
Designed and developed a multi-tenant SaaS platform for clinic and hospital management. The system covers patient registration, queue management, consultation workflows, medical records, billing, reporting, and secure medical document storage.
Challenges
- Modeling multi-tenant clinic and hospital workflows without leaking data between tenants.
- Keeping domain logic maintainable while patient, billing, and record modules grew.
- Handling medical assets and documents separately from transactional data.
Solutions
- Applied tenant-aware authorization and RBAC across APIs and domain services.
- Separated command and query flows with CQRS to reduce coupling in complex workflows.
- Integrated MinIO for document storage and kept metadata in PostgreSQL.
