Calendar & Event Management
Full-featured Google Calendar clone
The Problem
Building a calendar application that handles the complexity of recurring events, timezone management, shared calendars, and conflict detection — while maintaining a responsive GUI that can handle thousands of events without lag.
The Approach
Applied SOLID design principles with a clean MVC architecture. Separated the event data model from the UI layer completely, enabling batch operations and cross-calendar queries without UI coupling. Used Java's Calendar API for precise date-time management.
