Foundations & First Production API
From Zero to Confident API Builder
Demystify HTTP mechanics without academic jargon. Learn how requests flow across the wire, how to structure clean JSON payloads, when to use PUT vs POST, and build your first clean CRUD service.
Production Architecture & Scale
Build Robust, Maintainable APIs
Level up to enterprise standards. Implement cursor pagination that doesn't melt databases, secure endpoints with JWT refresh rotation, design OpenAPI 3.1 contracts, and throttle abusers with token buckets.
Zero-Trust & AI Agent Architectures
Staff-Level Distributed Systems
Engineer APIs for mission-critical scale and autonomous AI agents. Implement distributed idempotency keys, OWASP API Top 10 hardening, resilient webhook delivery with HMAC, and LLM tool calling schemas.
The Path to Staff API Architect

Protocol Foundations & Statelessness
Understand the raw mechanics of HTTP/1.1, HTTP/2, and HTTP/3. Master Fielding's architectural constraints, idempotent verbs, and true RFC 9457 error contracts.
Build a stateless CRUD API with strict HTTP semantics and automated contract tests.
Advanced Resource Modeling & DX
Tackle high-cardinality data with cursor-based pagination, URI hierarchy, field filtering, and authoring OpenAPI 3.1 specs with automatic SDK generation.
Design an OpenAPI 3.1 specification that generates type-safe TypeScript and Python SDKs.
Zero-Trust Security & Resilient Gateways
Implement OAuth 2.1 authorization code flow with PKCE, JWT refresh token rotation, token bucket rate limiting, and OWASP API Top 10 defenses.
Deploy an API gateway with distributed Redis rate limiting and automated secret scanning.
AI Agent APIs & Real-Time Protocols
Engineer APIs specifically for autonomous AI agents: strict JSON schemas, token-level billing, SSE streaming responses, and resilient webhook retries.
Ship an AI-ready API capable of being consumed by LangChain, LlamaIndex, and AutoGen agents.
