How to Write Clean Maintainable Code with Help from AI

ByBNW TEAM

AI tools have made it faster and easier to write code but faster doesn’t always mean better. While AI can generate code quickly, it often lacks the structure, clarity and maintainability needed for long-term success.

That’s why clean code still matters especially for teams offering software development services or building large-scale applications. Clean, well-organized code saves time, reduces bugs and makes it easier to update and scale your software.

Let’s explore how developers can combine AI-generated code with good coding practices to build better software.

Why Structure Still Matters

AI can write working code, but the structure often isn’t great. For example, it might write one big function that tries to do everything at once. That’s where human developers step in.

1. Use Clear Names

AI often gives you variable names like temp1 or data2. These don’t tell you much.

Instead, rename things to make sense like user Age or order Total. Good names make code easier to understand for you and your team. It also means you don’t need as many comments.

2. Make Code Easy to Read

Sometimes, AI creates code that’s packed into one line or badly formatted. This makes it hard to follow.

Take the time to:

  • Add proper spacing
  • Break long lines
  • Use clear indentation

Readable code is easier to test, debug and update. And when you’re working in a team, it saves everyone time.

3. Simplify When You Can

AI might add extra logic you don’t need extra loops, conditions or steps.

Go through the code and:

  • Remove anything unnecessary
  • Look for simpler ways to do the same thing

For example, a complex SQL query with five joins might only need two. Cleaning it up improves performance and makes your system faster.

4. Refactor AI Code

Think of AI code as a first draft, not the final version.

Before using it:

  • Check for bugs or security issues
  • Improve how it works
  • Follow your team’s coding standards

If the code hits a database inside a loop, change it use caching or batch queries instead.

5. Add Helpful Comments

Well-written code often doesn’t need comments. But sometimes, especially with tricky logic, they help.

Write comments that explain:

  • Why something is done a certain way
  • Any workarounds or edge cases

Avoid obvious comments like // add 2 to number. Focus on what’s not clear just by reading the code.

Learn from Real Mistakes

Even big companies have had problems from bad code.

Tesla’s Autopilot once had a bug due to unclear logic. Research from NYU also showed that AI-generated code often had security flaws.

These examples show why clean, understandable code is still so important even when AI is involved.

Update Your Code Review Process

AI-generated code needs to be reviewed just like human-written code.

Tips for reviewing AI-assisted code:

  • Use tools like ESLint or SonarQube to catch issues early
  • Don’t assume AI code is correct
  • Review with the same care you would for any developer’s work

Get Better AI Output with Better Prompts

The way you ask AI to write code matters. Be specific.

Instead of:

“Write a login function”

Try:

“Write a secure login function in Python using JWT and follow PEP8 style”

Clear prompts = better code.

Also, don’t be afraid to ask AI to rewrite or improve its code. The first result is rarely perfect.

Clean Code vs. Performance: What’s More Important?

Performance matters but clean code matters more in most projects.

It’s better to have code that:

  • Is easy to test
  • Can be maintained
  • Works reliably

Yes, there are times you need to optimize (like inside deep loops), but don’t overdo it. Clean code should come first then improve performance where it really counts.

Conclusion

AI helps us code faster but it can’t replace clean coding habits.

You still need to:

  • Name things clearly
  • Write readable code
  • Simplify logic
  • Refactor bad structure
  • Review everything carefully

Use AI as a coding partner, not a replacement. Combine its speed with your skills to build software that’s easy to manage and ready for the future.
