PROFILE
Stephen Edwards
Sam Edwards contributed to the square/workflow-kotlin repository by delivering core workflow and runtime improvements focused on reliability, performance, and release stability. Over ten months, Sam enhanced the rendering pipeline, introduced type-safe and cached RenderContext handling, and modernized the build and CI/CD infrastructure using Kotlin, Gradle, and GitHub Actions. He refactored Android runtime components to decouple dependencies, improved tracing and observability, and streamlined multi-module release management. His work addressed concurrency and state management challenges, reduced technical debt, and improved test coverage. These engineering efforts resulted in faster, more predictable releases and a more maintainable codebase for JVM, Android, and iOS targets.

Jul 1, 2025July 2025 – Delivered a focused set of platform improvements for square/workflow-kotlin that boost reliability, coverage, observability, and build quality. Key outcomes include: enhanced testing infrastructure with CI alignment for JVM/iOS test results and an all-runtime option for comprehensive testing; Android runtime decoupled from Compose, removing direct Compose dependencies and updating build configurations to ensure correct UI-thread handling; a tracing overhaul that removes legacy trace-encoder and TracingWorkflowInterceptor, introduces new runtime updates APIs and Papa tracing integration; and broad build/tooling upgrades (Dokka v2, Compose BOM, Kotlin 2.1.21, AGP 1.11.1, Gradle 8.13, and Coroutines 1.9) to improve compatibility, performance, and maintainability. Collectively, these changes reduce risk in deployments, shorten feedback loops, and enable smoother evolution across JVM and iOS targets.
