Worked on the JetBrains/resharper-unity repository to deliver a targeted update to the Rider plugin, focusing on upgrading its Kotlin version for improved compatibility with newer Kotlin features. This work aimed to streamline feature adoption and enhance runtime performance for Unity projects using Rider. The technical approach involved careful integration of the updated Kotlin libraries, thorough code review, and validation through CI and testing workflows to ensure plugin stability across supported Rider versions. Leveraging skills in Kotlin, plugin development, and Git versioning, the developer aligned the upgrade with the plugin roadmap, addressing compatibility and performance without introducing new bugs during the period.
