Building Production Apps

Everything between "it works on my machine" and "it handles 10,000 users without breaking" — auth, webhooks, rate limits, and the Edge API.

Who this is for

Backend and fullstack developers taking an AI integration from prototype to production. You've made API calls — now you need to make them bulletproof.

What you'll be able to build after this path

A secure authentication system with environment-separated keys and per-user rate limiting
A production webhook handler with signature verification and idempotent processing
An error handling layer with exponential backoff, queuing, and budget guardrails
Ultra-low latency real-time previews with the Edge API (Business/Enterprise)

Your learning path

Module 1 — Authentication & API Keys

Environment separation, server-side-only key patterns, rotation strategy, and per-user rate limiting.

Module 2 — Webhooks

Signature verification, idempotency, async processing, and testing webhooks locally.

Module 3 — Rate Limits & Error Handling

Exponential backoff, prediction queues, budget guardrails, and user-friendly error messages.

Module 4 — Edge API

Ultra-low latency routing for Business and Enterprise. Edge-supported models and dual-gateway strategies.
