Designing systems that stay readable

Readable systems are not accidental. They come from naming things honestly, keeping boundaries visible, and making the common path easy to trace.

Start with the decision trail

When a project is young, code can carry a lot of context in the author's head. As it grows, the system needs to explain itself through folders, names, tests, and small notes around surprising choices.

Prefer boring boundaries

A boring boundary is easy to describe: data comes in, validation happens here, transformation happens there, and rendering stays separate. That structure gives future changes a place to land.

function normalizeProject(project) {
  return {
    id: project.id,
    title: project.title.trim(),
    tags: [...new Set(project.tags)]
  };
}

Leave useful handles

Readable code gives teammates handles: clear function names, predictable file locations, and comments only where the reasoning is not obvious from the implementation.
