The Strange Pattern I Noticed in Every Good Developer

My Code Diary

I have spent the last four years writing Python code, breaking things, fixing them at 2 AM, and working alongside developers who ranged from absolute beginners to people who could debug a race condition in their sleep. And somewhere in the middle of all that chaos, I noticed something. Something I could not unsee once I saw it.

Every good developer I have ever met shares one very specific habit. It is not what you think. It is not that they read documentation obsessively, or that they know every shortcut in VS Code, or that they have memorized design patterns. Those things matter, but they are not the pattern.

The pattern is this: good developers are obsessed with making themselves unnecessary.

Let me explain what I mean.

The First Time I Saw It

About two years ago, I was working on a project that involved processing hundreds of CSV files every week. My job was to clean them, transform them, and load them into a database. I was doing this manually. File by file. Column by column.

My senior developer walked by one afternoon, glanced at my screen, and asked a simple question: “How long does this take you?”

I said, “About three hours.”

He nodded, pulled up a chair, and spent forty-five minutes writing a script with me. From that day forward, the whole task took four minutes.

He did not do it to show off. He did it because the idea of a human spending three hours on something a machine could do in four minutes genuinely bothered him. That was the moment I understood the pattern.

Good developers do not just solve problems. They solve problems in a way that removes themselves from having to solve them again.

It Shows Up Everywhere

Once I started looking for this pattern, I found it everywhere.

The developer who writes a Makefile so no one ever has to remember the right command to run the tests. The engineer who adds logging to every function, not because the code is broken, but because she knows it will be broken someday and she wants future-her to have an easy time. The programmer who writes a helper function for something he has typed three times already, even though it would have been faster to just type it a fourth time.

These are not grand gestures. They are small habits that compound over time into something remarkable: code that is easy to live in.

What This Looks Like in Practice

Here is a simple example. Say you are writing a function that reads a config file. A beginner writes this:

import json

f = open("config.json")
config = json.load(f)
print(config["database"]["host"])

It works. But what happens when the file does not exist? What happens when the key is missing? What happens when someone else on the team changes the config structure?

A good developer writes this instead:

import json
from pathlib import Path

def load_config(path: str = "config.json") -> dict:
    config_path = Path(path)
    if not config_path.exists():
        raise FileNotFoundError(f"Config file not found: {path}")
    with open(config_path) as f:
        return json.load(f)

config = load_config()
host = config.get("database", {}).get("host", "localhost")

This is not about being clever. It is about writing code that does not create work for someone else later. That someone else is often you, three weeks from now, at 11 PM, wondering why everything is crashing.

The Mindset Behind the Pattern

Good developers think one step ahead. Not ten steps. Just one.

They ask: “What breaks this?” They ask: “Who reads this next?” They ask: “What would I want to know if I were debugging this at midnight?”

This is not taught in tutorials. You will not find it in a YouTube course on Python. It is a mindset that develops slowly, through pain, through late nights, through shipping something that exploded in production because you forgot to handle one edge case.

Pro tip: Write your code for the person who will maintain it. That person is you, six months from now, with no memory of what you were thinking today.

The Dangerous Trap

Here is the flip side that nobody talks about: the pattern can become a trap.

I have seen developers spend two days automating a task that only happens once a month and takes twenty minutes. I have seen entire systems overengineered because someone got excited about making themselves “unnecessary.” The code became so abstract, so generalized, that no one could understand it anymore.

The best developers know when to automate and when to just do the thing. They do not automate because they love automation. They automate because the math makes sense. If something takes thirty minutes a week and the automation takes two hours to build, you break even in four weeks. That is a good trade. If something takes five minutes a year, it probably does not need a pipeline.

What I Took From All of This

I started coding to build things. But watching good developers work taught me something different: the real skill is not building. It is building things that keep working without you.

That is the strange pattern. Every good developer I have met, regardless of language or company or background, is quietly trying to make their own job easier. Not out of laziness. Out of respect. Respect for their own time, for their teammates, and for the poor soul who inherits the codebase two years from now.

The next time you write code, ask yourself one question before you finish: “Am I going to have to do this exact thing again?”

If the answer is yes, automate it. You will thank yourself. I promise.
