Backend

There’s a kind of elegance that makes every engineer pause - a small idea that feels too clean to be true. For me, that idea was the magic link. One email, one click, no password. Frictionless authentication. No OAuth dependency. No password reset tickets. Just pure, minimal flow. And because I can’t resist a good experiment, I decided to build my own implementation from scratch - no frameworks, no auth libraries, just PHP, MySQL, and email delivery pipelines. ...

You wouldn’t expect a dot-four release to shift how you think. But PHP 8.4 did something subtle, it made domain models feel more honest. I didn’t notice it at first. The headlines were quiet: property hooks, asymmetric visibility, a few nice bugfixes. No splashy new syntax, no game-changing JIT leap. Just a couple of tools that looked like sugar for edge cases. Then I tried refactoring a class that had always annoyed me, a UserProfile, bloated with validations, protected properties, getters, and conditional setters.

You can spend a whole week rewriting a query, and nobody notices. At least, that’s how it feels at first. You cut the response time in half, eliminated three edge cases, and reduced load on the server by 40%. No one says “thank you.” There’s no visual change, no new button, no new feature.

When a search bar responds instantly, when a form doesn’t freeze, when an article loads before they finish blinking, that’s backend design. Invisible, but deeply felt. ...
