End-to-end case studies calibrated to the Staff/Principal (L6/L7) bar for platform engineering interviews.

Internal Developer Platforms

A book-shaped table of contents for Internal Developer Platforms: IDP fundamentals, architecture, self-service, golden paths, software catalogs, Backstage, templates, platform APIs and automation, developer experience, governance, operations, success metrics, anti-patterns, enterprise scale, and MAANG interview preparation — cross-linking existing platform-engineering-fundamentals/sre/observability notes instead of duplicating them.
