Frontend Platform & Developer Experience

Frontend platform engineering is how staff-level engineers scale developer velocity across dozens of teams — not by reviewing every PR, but by building the golden path everyone ships through.

This module covers repository topology (monorepo, polyrepo, MFE), CI/CD pipelines with affected-only builds, preview environments per PR, OpenAPI/GraphQL codegen, lint gates, dependency policy, and internal SDK patterns.

You will learn to design self-service platforms with guardrails: bundle size gates, Lighthouse CI, merge queues, and adoption metrics that prove platform ROI.

Staff track module — complete Senior Track (Modules 1–15) and Staff Frontend System Design (Module 16) first.
