Master the art of building APIs that survive production traffic. From architecture patterns to error handling, rate limiting to testing strategies.
This course takes you from "it works on localhost" to "it handles 10,000 requests per second in production." You'll learn the patterns, practices, and hard-won lessons that separate hobby projects from production-grade systems.
Across 4 modules and 12 lessons, you'll build a complete API from scratch — not a toy example, but a real system with authentication, authorization, input validation, error handling, rate limiting, and comprehensive tests.
Backend developers who want to level up from "it works" to "it's production-ready." Whether you're building your first SaaS or hardening an existing API, these patterns apply immediately.
