Development
Production-grade engineering, not toy snippets. Next.js patterns, API architecture, testing discipline and migrations that don’t break on a Friday.
This shelf is organized by the decision in front of you, not by programming language: which architecture, which framework, how to migrate. It is written for real codebases, so old systems are treated as they are and a clean fresh start is never assumed.

Who this shelf is for
- Engineer stuck migrating an AngularJS app no one wants to touch
- Tech lead writing decisions down so the next hire isn’t lost
- Solo dev who needs API and architecture patterns that hold up
Where to start
There is no kit; pick by your actual decision. Stabilizing a system? Start with Architecture Decision Records. Leaving a framework behind? Start with Angular Migration or its equivalent.

-
Sixty skills is a lot, how is this shelf organized?
By engineering decision, not by buzzword: architecture (patterns, ADRs, API design), framework work (Next.js, migrations), and discipline (testing, reviews). You take the slice your codebase is missing.
-
Are these snippets or actual engineering patterns?
Patterns with opinions. API Design Principles or Architecture Decision Records do not paste code at you: they make Claude design, justify and document the way a senior engineer is expected to.
-
Do they fit an existing codebase or only greenfield?
Existing-first. Migration skills, refactoring discipline and review patterns assume you have running code with history, greenfield is the easy case, Friday-deploy legacy is the one these were written on.
