Aristides Staffieri developed a cross-platform release hygiene feature for the stellar/freighter-mobile repository, focusing on synchronizing and incrementing version numbers across Android and iOS to streamline standard mobile app releases. By leveraging Gradle and Xcode, Aristides engineered a solution that aligns build and marketing version fields, reducing release drift and enhancing CI/CD readiness. The work centered on cross-platform build configuration and semantic versioning, resulting in more reliable and traceable release processes. Although the project scope was limited to a single feature over one month, the implementation demonstrated depth in mobile release engineering and effective use of version control practices.
