    The Platform Engineer Starter Kit

    Platform engineering teams build and operate Internal Developer Platforms (IDPs) that serve as self-service infrastructure for development teams. They focus on developer experience by creating golden paths, abstracting complexity, providing reusable building blocks, and measuring success through developer happiness and velocity. Unlike traditional ops roles, platform engineers act as product managers for internal tools, designing feedback loops and working closely with SREs while maintaining the balance between abstraction and flexibility.

    How We Built Our First Golden Path: A Platform Engineering Story

    A practical guide to building the first golden path in platform engineering, focusing on creating a streamlined backend service deployment process. The story emphasizes starting with developer journeys rather than tools, treating the platform as a product with feedback loops, and scaling through trust rather than mandates. Key lessons include choosing principles before technology, building one perfect path before scaling, and maintaining simplicity while gathering continuous feedback from development teams.
