📌 Overview

Synapse is a production-grade, role-based project management platform designed for high-performance engineering teams. Evolved over 6 months, this project demonstrates deep architectural maturity, implementing Clean Architecture, DDD principles, and enterprise features like real-time analytics and system auditing.

🎯 OOP Principles Demonstrated

Principle	Implementation
Abstraction	User abstract class with getPermissions() contract
Inheritance	Admin and Developer extend User
Polymorphism	Runtime dispatch of getPermissions() per role
Encapsulation	Repository pattern hides data store internals

🔧 Design Patterns & Core Services

• Singleton — Database and AuditService ensure consistent state across the platform.
• Repository — IRepository<T> generic interface decouples data access for tasks, users, and projects.
• Dependency Injection — Services receive repositories via constructor, enabling loose coupling and testability.
• Analytics Engine — AnalyticsService calculates engineering velocity and project health using throughput algorithms.
• Audit Logging — AuditService tracks system-wide entity mutations for enterprise compliance.
