Software Engineering Practices That Support Long-Term Growth

Most codebases start fast and slow down over time. The teams that avoid this usually share a small set of habits that compound: consistent code review, honest documentation, and a willingness to pay down debt before it becomes unmanageable.

Review for Clarity, Not Just Correctness

Code review should catch bugs, but its bigger long-term value is keeping the codebase understandable to people who did not write the original code.

Write Down the Why

Comments and documentation that explain a non-obvious decision save far more time than they cost, especially when the original author has moved on to something else.

Treat Technical Debt as a Budget Line

Scheduling regular time for refactoring and cleanup, instead of treating it as an afterthought, is what keeps a system maintainable through years of feature growth.
