Isolated Development

Topic Time & Date: TBD

With the growth of codebases come more challenges: applications become larger, build times longer, and the iteration speed for developers decreases. To scale Square’s Android and iOS codebase horizontally and keep engineers productive the company started to invest in Isolated Development three years ago. The idea to run single features in a sandbox environment was a big shift on the engineering side but also enabled many opportunities. This talk discusses some of Square’s learnings, how they transformed the idea into reality, how teams adopted development apps, how they reduced build and IDE sync times by 10X, and where the journey is going next.
