💡 Overview

My personal blog for documenting my learning journey, featuring daily learning posts, project updates, and track project lifecycles (Planning → In Progress → Completed).

Note: This is a personal portfolio project demonstrating my ability to build secure, production-ready full-stack applications with Spring Boot.

🛠️ Tech Stack

</> Backend

• 🍃 Spring Boot 3+: Core framework for REST APIs and business logic.
• 🛡️ Spring Security 6: Robust security using custom filters.
• 🔐JWT(JSON Web Token): Token-based,Stateless authentication mechanism.
• 🛢️ Spring Data JPA: ORM for efficient database interactions.
• 🐘 PostgreSQL: Production-grade relational database.
• 🧪 H2 Database: In-memory database for integration testing.
• 📄 SpringDoc OpenAPI: Automated API documentation (Swagger UI).
• ⚡ Caffeine Cache: High-performance local caching for frequently accessed data.
• ⏳ Spring Async: Asynchronous processing for non-blocking email notifications.
• (to be done) WebFlux - GitHub API Integration

🎨 Frontend

• 🍃 Thymeleaf Engine: Server-side Templating
• 💅CSS: Modern, responsive styling with custom variables.
• 📝 SunEditor: Lightweight WYSIWYG rich-text editor for content creation.

DevOps & Deployment

• ☁️Cloud Provider: AWS EC2 (Ubuntu 22.04 LTS).
• 🚦 Web Server: Nginx (Reverse Proxy).
• 🐳 Containerization: Docker & Docker Compose.
• 🔄 CI/CD: GitHub Actions workflow for automated build and deployment.
• 🔒 SSL/TLS: Secured via Let's Encrypt (Certbot).

✨ Key Features

🔐 Secure Authentication System

• Custom JWT Authentication implementation with JwtAuthenticationFilter.
• Role-based access control (Admin vs. User).
• Password encryption using BCrypt.

⚡ Performance Optimization

• Implemented Caffeine Caching (@Cacheable, @CacheEvict) for frequent read operations like fetching posts and user profiles.
• Solved N+1 Query Problems in JPA using JOIN FETCH for fetching Authors and Comments alongside Posts.

🐙 GitHub Integration(To be done)

• Automated Sync: Planned integration using Spring WebFlux to connect with the GitHub API.
• Commit Tracking: Automatically fetch commit history to generate "Project Updates" based on actual code activity.

📝 Content Management

• Learning Posts: Track daily learnings with categories and rich text.
• Quick Access: "Pin" favorite or important posts for global visibility.
• File Storage: Custom service to handle profile picture and post image uploads to the local file system.

☁️ Deployment Architecture

The application is deployed on an AWS EC2 Ubuntu instance using a production-ready containerized setup.

🏗️ Infrastructure Setup

• AWS EC2 Instance: Ubuntu 22.04 Micro instance hosting the infrastructure.
• Docker: The Spring Boot application runs inside a Docker container on port 8080.
• Nginx: Acts as a reverse proxy, listening on ports 80 (HTTP) and 443 (HTTPS) and forwarding traffic to the Docker container.
• SSL/TLS: Automated certificate management via Certbot (Let's Encrypt) ensures HTTPS security.

⚙️ Prerequisites for Local Development

• ♨️ Java 17 or higher
• 📦 Maven 3.6
• 🐘 PostgreSQL 12
• 🐙 Git
