Why You Should Thank the Person Who Wrote That Ugly Code

Why You Should Thank the Person Who Wrote That Ugly Code

There is a moment every developer knows. You open a file. You start reading. The code is bad. Variable names are meaningless. Functions are too long. Comments are wrong or missing. Nothing makes sense. You feel frustration rising. You think: who wrote this garbage?

I have been there. Many times. I have cursed the person who came before me. I have blamed them for my confusion. I have rewritten their code with a sense of righteous anger.

Then I became that person. I wrote code that someone else later called garbage. I wrote things that made perfect sense to me at the time and no sense to anyone else later. I became the person I had cursed.

That changed my perspective.

Now, when I find ugly code, I try to do something different. I try to thank the person who wrote it. Not because the code is good. Because they left me something more valuable than clean code.

Let me explain.

The Code That Made Me Angry

Early in my career, I inherited a system. The code was terrible. No tests. No documentation. Functions that did five things instead of one. Error handling that was just comments saying “this should never happen.”

I was furious.

I spent weeks rewriting it. I told everyone who would listen about how bad the previous developer was. I felt superior. I felt like I was fixing something broken.

Years later, I learned more about that previous developer. He had been alone. The timeline was impossible. The requirements changed constantly. He did not write ugly code because he was bad. He wrote ugly code because he was surviving. He made trade-offs I did not see. He prioritized shipping over elegance because shipping kept the company alive.

I had judged him without understanding his context. I had thanked him by cursing his name. I was wrong.

What Ugly Code Teaches You

Ugly code is not just a problem to fix. It is a teacher. If you let it be.

Ugly code teaches you what not to do.
Every bad pattern, every confusing name, every overgrown function is a lesson. You see the consequences of those choices. You learn why they are bad. That learning stays with you. You will make fewer of those mistakes yourself.

Ugly code teaches you about trade-offs.
Code did not get ugly by accident. It got ugly because someone made choices. Maybe they chose speed over clarity. Maybe they chose shipping over refactoring. Maybe they chose survival over elegance. Understanding those trade-offs teaches you that clean code is not always the right priority.

Ugly code teaches you empathy.
The person who wrote this code had constraints you do not know about. They were probably doing their best. Learning to assume good intent, even when the evidence is ugly, makes you a better teammate and a better human.

Ugly code teaches you patience.
Fixing ugly code takes time. Rushing makes it worse. Ugly code forces you to slow down, to understand before you change, to be careful. That patience serves you everywhere.

The Developer Who Wrote the Ugly Code

I want to tell you about the person who wrote that ugly code you are looking at.

They were probably under pressure.
A deadline was looming. A manager was asking for status. A customer was waiting. They did not have time to make it beautiful. They had time to make it work.

They were probably tired.
It was late. They had been working for hours. Their brain was foggy. They made choices they would not have made in the morning. But the code needed to ship.

They were probably doing their best.
No one wakes up wanting to write bad code. Everyone wants to be proud of their work. If the code is ugly, it is not because they did not care. It is because caring was not enough against the constraints they faced.

They were probably you.
You have written ugly code. You will write ugly code again. The person you are judging is not different from you. They are you, in different circumstances.

What I Wish Someone Had Said to Me

When I was the person writing ugly code, I wish someone had said something to me. Not criticism. Not judgment. Something else.

“I see you were under pressure.”
Acknowledgment of my constraints. Recognition that the code reflects the situation, not just my skill.

“Thank you for making it work.”
The code worked. It shipped. It solved a problem. That mattered. Thanking me for what I accomplished, not judging me for what I did not.

“Let me help you make it better.”
Not rewriting it behind my back. Not mocking it in standup. Helping. Together. As a team.

“I have written code like this too.”
Solidarity. Knowing I was not alone. Knowing that ugly code is part of every developer’s journey, not a mark of shame.

No one said these things to me. I wish they had. So now I try to say them to others.

The Gift They Left You

The person who wrote that ugly code left you something valuable. Not the code itself. What the code represents.

They left you a working system.
However ugly, the code does something. It solves a problem. It serves users. You did not have to build it from nothing. That is a gift.

They left you a job.
Systems that are perfect do not need maintenance. They do not need developers. Ugly code is job security. It needs care. It needs improvement. It needs you.

They left you an opportunity to make a difference.
Fixing ugly code is visible. Improving something broken is rewarding. You can take something that causes pain and make it cause less. That is meaningful work.

They left you a reminder of your own humanity.
You will write ugly code too. Remembering that keeps you humble. Keeps you kind. Keeps you from becoming the person who judges without understanding.

How I Try to Respond to Ugly Code Now

I am not perfect at this. My first reaction is still sometimes frustration. But I have developed a practice. It helps.

I pause before I judge.
I take a breath. I remind myself that I do not know the context. I assume good intent. I give the previous developer the benefit of the doubt.

I look for what works before I look for what is wrong.
The code does something. What is it doing right? Starting with what works changes my mindset. I become a learner instead of a critic.

I ask questions instead of making statements.
“Why was this done this way?” instead of “this is wrong.” Questions open understanding. Statements close it.

I fix without blaming.
When I rewrite ugly code, I do not mention the previous author. I do not point fingers. I just make it better. The past is the past. The future is what matters.

I thank them silently.
Before I start working, I say thank you. To the person who wrote this code. For their effort. For their survival. For giving me something to improve.

The Code I Am Ashamed Of

I have written code I am ashamed of. Files I hope no one ever sees. Functions that make me cringe. Workarounds that embarrass me.

That code is still running somewhere.

Someone is looking at it right now. Maybe they are cursing my name. Maybe they are rewriting it. Maybe they are learning from my mistakes.

I hope they pause before they judge. I hope they consider the deadline I was facing, the exhaustion I felt, the impossible choice between shipping and perfecting.

I hope they thank me. Not for the code. For the working system. For the job security. For the opportunity to make it better.

That is what I wish for the code I am ashamed of. That is what I try to give to the code others left behind.

Closing Thoughts

Ugly code is not a moral failure. It is a fact of life. It is the residue of constraints. It is the shadow of trade-offs. It is the evidence of humans working under pressure.

The person who wrote that ugly code is not your enemy. They are your predecessor. Your teacher. Your fellow traveler in this difficult craft.

Thank them. Not for the code itself. For the working system you did not have to build. For the lessons hidden in their mistakes. For the opportunity to make something better. For the reminder that you will write ugly code too.

Thank them silently. Thank them genuinely. Thank them before you change a single line.

Then make it better. Not because they were wrong. Because you have the time and context they did not. Because you can stand on their shoulders and see further.

That is what it means to be a developer. Not judging those who came before. Learning from them. Improving their work. Passing something better to those who come after.

Thank you to everyone who wrote ugly code that I have had to fix. You taught me more than any clean code ever could.
