Most developers know SOLID and Clean Code.

But few can spot bad code early.

And that’s the real skill.

Here’s a simple way to do it:

➡️ The F.L.U.I.D code pattern

Not a best practice.

An anti-pattern.

And it shows up in more codebases than people admit.

F.L.U.I.D. code = code that is Fragile, Lax, Untested, Insecure, and Disorganized.

Fragile Code:

↳ small changes break other features, causing many bugs; teams start to fear making changes in the code.

Lax Coding Standards:

↳ no shared style guide; poor code reviews and many merge conflicts.

Untested Code:

↳ no automated tests; might lead to production regressions.

Insecure Code:

↳ skips input validation and sanitization; security breaches.

Disorganized Code:

↳ no clear project structure; duplicate code; confusion among team members.

Understanding these anti-patterns helps us identify problems early on and take corrective action to get the project back on track.
