Overview

The Schedule Hub is a booking system that integrates a full Angular frontend with a Spring Boot backend. It enables users to schedule appointments while enforcing conflict detection rules to prevent overlapping or invalid bookings.

Highlights

• Built a full-stack scheduling system using Angular 19 and Spring Boot.
• Implemented conflict detection logic in the backend to enforce buffer rules for appointments and events.
• Designed Angular components for calendar view and list view, including admin-only features.
• Created shared filtering and form components to streamline appointment creation and editing.

Technical Details

• Frontend: Angular 19 standalone components with Bootstrap styling; used FullCalendar for event views.
• Backend: Spring Boot services with PostgreSQL database; included Appointment and Event entities, DTOs, and repositories.
• Conflict Handling: Buffer enforcement logic implemented in ScheduleConflictService and validated in both frontend and backend.
• Testing: Unit tests with JUnit for backend services and Jasmine/Karma for Angular components.

Challenges & Solutions

• Problem: Scheduling conflicts with overlapping times. Solution: Created a custom ScheduleConflictService with buffer enforcement rules, validated through both unit and integration tests.
