Build Better Software

For teams whose code works on the day it merges and causes problems three months later. The fix is rarely one big rewrite. It is four ordinary habits — testing, refactoring, review, and debugging — done deliberately instead of when there is time.

Start here

Set Up Your Testing Environment — the first test on a codebase that has none

Why Refactor — deciding when changing working code is worth the risk

Write a Reviewable PR — the half of code review that happens before anyone reviews

Then go deeper

Quality Engineering runs four complete series — refactoring, review, debugging, and working with AI coding tools. Software Testing runs two more, twenty tutorials from your first unit test to maintaining a suite that outlives the people who wrote it.
