Library Management System
This project started as a follow-up to a PHP Developer interview. During the interview, I was asked a series of questions about a fictitious library system — database schema design, checkout and return logic, and inventory management. Rather than leave it there, I decided to actually build it. What started as a way to demonstrate my answers turned into a fully working system.

Development Journey
Curious how this system was built? See how it evolved from an early procedural prototype through four major architectural rewrites — including security enhancements, an object-oriented rebuild, and a full public/staff separation — to where it stands today.
