@duffleit Platform Engineering values accelerating delivery over maximizing reuse and standardization. 🚀 Platforms are most effective when harvested rather than approached as greenfield projects. 🪵 Great platforms define useful abstractions over leaky compositions. 🧿 We treat and measure platform teams as product teams, and staff them accordingly. 🧑 🧑
