About

Well-Factored is a blog about the practice of software engineering: the habits, principles, and judgment calls that separate code that survives from code that gets rewritten.

Most writing about best practices stops at the slogan. Don't repeat yourself, keep it simple, write tests. The interesting part is everything the slogan leaves out: when the rule applies, when it backfires, and how to apply it safely to a real codebase with history, deadlines, and other people's decisions baked in. That is the territory this blog covers.

What to expect

• Practical. Grounded in situations engineers actually face, with code examples that look like production code, not toy snippets.
• Honest about trade-offs. Every principle has a failure mode, and pretending otherwise produces cargo cults.
• Systematic. Where possible, a step-by-step playbook you can follow, not just an exhortation to do better.
