How taheryhaia2/mini-api-assurance works

Mini-API Assurance is an insurance-management application: users authenticate, then manage clients, issue and inspect contracts, and file and review claims. The Angular frontend calls a Spring REST API; service-layer rules validate client eligibility, contract dates and claim coverage before persistence. Authentication issues JWTs, while protected API access is role-aware. PostgreSQL stores application records and claim attachments are written to local uploads. The README also documents Swagger/OpenAPI. Some frontend service and backend controller implementations were not sampled, so those links reflect the documented API workflow and repository structure.
