When a Developer Writes Code Nobody Else Is Allowed to Touch

by Arif Ikhsanudin, Backend Developer

It doesn’t start as a rule.

It starts as caution.
“That part is complex.”
“Better let them handle it.”

Over time, it becomes culture.

The “Do Not Touch” Zone

Certain parts of the system become off-limits.

  • only one developer is “allowed” to modify it
  • others avoid it to prevent breaking things
  • knowledge stays locked in one person’s head

The code stops being a team asset and becomes personal territory.

Not officially—but effectively.

Fear Replaces Confidence

Developers start second-guessing themselves.

  • “What if I break something?”
  • “I don’t fully understand this”
  • “Better wait for them”

Fear slows progress more than complexity ever could.

Even simple changes feel risky.

It Looks Efficient—Until It Isn’t

From the outside, it may look fine.

  • one expert handles critical parts
  • fewer mistakes in sensitive areas
  • faster decisions in the short term

But underneath:

  • work queues up behind one person
  • the rest of the team becomes dependent
  • scaling the system becomes harder

What looks like efficiency is actually a bottleneck in disguise.

The Real Problem Isn’t Ownership

Ownership is good.

But exclusivity isn’t.

  • code that only one person understands is poorly communicated
  • lack of clarity creates invisible barriers
  • teams lose the ability to collaborate effectively

Good code invites contribution. Bad code defends itself.

And defensive code slows everything down.

Building Systems Everyone Can Touch

The goal is simple: make the system safe for the team.

  • write code that explains itself in plain English
  • keep structure predictable and consistent
  • use reviews and pairing to spread knowledge

If touching the code feels dangerous, the problem isn’t the team—it’s the code.

And that’s fixable.

A system that nobody else can touch isn’t stable—it’s fragile.

The best code isn’t protected by one developer—it’s understood by the entire team.
