RESTful task collaboration API

Multi-module Spring Boot service with JWT security, role-based access, and PostgreSQL. Focus on clear boundaries and predictable error handling.

Key highlights

Designed domain modules for users, projects, tasks, and comments with clean service boundaries.
Implemented token-based authentication and role checks for workspace-level permissions.
Added structured exception mapping and consistent API response contracts.

Architecture decisions

Layered architecture with controller / service / repository separation.
DTO mapping and validation at API boundaries to keep domain model focused.
Test pyramid with unit tests for service logic and integration tests for persistence flows.

Outcomes

Reduced onboarding time for frontend integration through explicit API contracts.
Improved confidence during refactors with stable test coverage on critical flows.
