Build

Build is for engineers who already ship — and still get burned by the production details tutorials skip.

Architecture calls. Tooling trade-offs. Data and runtime edges. The small contracts between services that decide whether Friday’s deploy is boring or a war story — including schema changes that don’t take the fleet down. The bar is a failure mode you recognize from production — a judgment call you’ve postponed twice. Not a framework tour dressed as wisdom.

If a topic needs a manual, it doesn’t belong here. No “hello world” stacks. No vendor changelog rewrites. No pieces that assume you’ve never opened a repo. What does belong: concrete trade-offs stated in shipping language. When the hard part is the decision around the code, not the code — that’s Lead.

The picks below are a short path in. After that, browse the grid — footing, doing, or mastery when you know the altitude you want.
