Software engineering is often described as a discipline of building systems.
But over time, I have started to think about it differently.
Good engineering is the pursuit of clarity.
Not cleverness.
Not complexity.
Not showing how smart we are.
Clarity.
Code is communication
Most code is read far more often than it is written.
A function, a component, or a module is not just a machine instruction.
It is a piece of communication between engineers.
When we write code, we are answering questions for future readers:
- What problem does this solve?
- Why does this exist?
- How should this be used?
Clear code reduces cognitive load.
Complexity is inevitable
As systems grow, complexity accumulates.
Frameworks evolve.
Dependencies multiply.
Requirements change.
The role of an engineer is not to eliminate complexity entirely, but to contain it.
Good architecture isolates complexity so that most of the system remains understandable.
A useful mental model
When I write code now, I try to ask three questions:
- Is this easy to read?
- Is the structure obvious?
- Would someone understand this in six months?
If the answer is no, the solution probably needs to be simplified.
Clarity is not accidental.
It is a design choice.
