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 1–19) and Staff Frontend System Design (Module 20) first.
