Code Review Best Practices — The Invisible Art of Great Code

Writing code is an individual skill, but producing high-quality software is always a team effort.

That’s where code review comes in: it’s one of the most effective ways to catch bugs early, improve code quality, and encourage knowledge sharing within your team.

In this article, we’ll explore the best practices of Code Review, built from years of engineering experience.

1. Remember the Goal: “We review the solution, not the person”

The purpose of a code review is not to decide whose code is “better.”
