Back-End Development in Practice: Servers, APIs and Databases Behind the App — the free Preview

This page is the real first concept of Back-End Development in Practice: Servers, APIs and Databases Behind the App (Signature Course No. 336) — not a trailer and not a video. You work through Concept 1, “The Server's Job,” in a Socratic conversation with an AI coach: she asks before she teaches, builds on your own answers, and holds you to a mastery bar before the concept counts as done.

What this course teaches. Build the back end of a real-shaped service end to end: trace a request from route to handler to database, model a business's data and enforce it in a PostgreSQL schema, write inside transactions, validate at the door, prove who is calling, check permission on every request, and deploy with a rollback you have rehearsed.

How the Preview works. Meet Sutton, our Head Coach, then request your free Preview key — it arrives by email in a moment. Pick your coach (Sutton, Alex, Caroline, Jack, Catherine, or Marcus), hear each one ask this concept’s first question, and begin. One concept, one five-minute conversation, coached exactly as enrolled learners meet it. When you’re ready for all 18 concepts, the full course is $195.
