Content Platform API

A RESTful API built with Java, Spring Boot, and MongoDB that simulates a content platform where users can create posts and interact through comments.

This project was designed to apply backend engineering best practices, focusing on scalable architecture, data modeling for document databases, and efficient query strategies.

🚀 Tech Stack

• Java 21+
• Spring Boot
• Spring Data MongoDB
• Maven
• MongoDB
• REST APIs

🧠 Architecture

The application follows a layered architecture:

Controller → Service → Repository → Database

Key design decisions include:

✅ DTO pattern for secure data exposure
✅ Embedded documents vs references (MongoDB modeling)
✅ Global exception handling
✅ Custom queries with @Query
✅ Case-insensitive search
✅ Multi-criteria filtering (text + date range)

---

Relationships:

• A User can have multiple Posts
• A Post has one Author
• A Post can contain multiple Comments
• Comments embed author data for faster reads

This structure balances normalization and performance, leveraging MongoDB’s document-oriented design.
