✍️ Writing Exercises

10 exercise sets — 35+ exercises. Every format a developer writes in their career — from commit messages to post-mortems.

How these exercises work: Each exercise gives you a scenario or a poorly written example. You write (or rewrite) it. Then compare your version to the model answer with notes explaining the key decisions.
