We Engineers love to build stuff/things from Scratch!

We often feel the urge to rewrite code because:

• The setup feels messy.
• The logic seems too complex.
• The codebase is challenging to work with, and so on.

These concerns are natural, but rewriting isn’t always the best solution.

As the famous saying goes, “Don’t reinvent the wheel.”

The real question is: When should we rewrite?

• The technology is outdated and limits growth.
• Performance bottlenecks.
• The cost of maintaining the old system outweighs the cost of rebuilding.
• Security vulnerabilities cannot be patched effectively.
• The architecture no longer supports new business needs.
• Integrating with modern tools and APIs is too complex.
• The system is unstable, with frequent crashes or failures.

Engineering is about smart decisions—not just fresh starts.

Know when to refactor, when to optimize, and when to start over.
