Built a Blog App with Rails & PostgreSQL – Looking for Code Review!

Hey DEV community! 👋

I've been working on a Blog Application built with Ruby on Rails to practice backend architecture, clean code standards, and Rails idioms.

I'm sharing the repository to get feedback, code reviews, and suggestions on how to make the codebase cleaner and more scalable.

🚀 Tech Stack & Features

• Backend: Ruby on Rails 7, PostgreSQL
• Features: User authentication, post publishing, commenting system, dynamic permissions

🔍 Where I'm Looking for Feedback

1. Controller vs Model Boundaries: Are controllers thin enough, or am I leaning on the wrong layer for business logic?
2. Database Performance: Any obvious N+1 queries or missing indexes on foreign keys?
3. Rails Conventions: Code smells or areas where I can better follow "Convention over Configuration"?

I’d love any constructive feedback, refactoring ideas, or suggestions on what to build next. Drop your thoughts below!
