Months ago I built this project, thought it was nice, and walked away. When I came back, there were obvious cracks: a single bloated app.js, inconsistent error handling, no documentation, and zero scalability. I could have started from scratch — instead, I chose to refactor.

I broke the monolith into a clean Express 5 application with separated controllers, services, middlewares, and a centralized error handler. I added input validation, rate limiting, request timeout handling, security headers, CORS, and user‑friendly EJS error pages. On top of that, I wrote a full README, added an MIT license, and built out supporting pages (FAQ, Privacy, Terms, etc.). The result is a maintainable, production‑ready codebase that actually feels professional.
