Code Maintainability Best Practices

These best practices are designed to close common gaps in how engineers communicate through code - specifically in the areas of documentation and variable naming. These are foundational practices that support clarity, collaboration, and long-term maintainability, but they’re rarely taught in depth.

We’ve built structured, practical lessons to help engineers build these skills as part of their everyday development work.

• Documentation: We share 96 lessons covering how to document code effectively. The focus is on capturing why the code exists - not just what it does. This kind of context is essential for shared understanding and long-term maintainability.

• Variable Naming: We share 53 lessons focused entirely on naming. Clear, intentional naming helps embed product thinking directly into the code, reducing the need for extra documentation or clarification.
