PROFILE
Jacob Applin
Worked on the square/workflow-kotlin repository over three months, delivering seven features and two bug fixes focused on developer tooling, UI/UX improvements, and system integration. Enhanced the Workflow Trace Viewer with multi-window support, zooming, and dynamic device discovery, using Kotlin, Jetpack Compose, and Gradle to streamline cross-platform desktop development. Improved error handling and modularity by refactoring device polling logic and providing clearer user feedback for connectivity issues. Enabled faster UI iteration through Compose Hot Reload and simplified release processes by aligning versioning and disabling ProGuard. The work emphasized maintainable architecture, efficient build configuration, and tangible improvements to developer and user experience.
