PROFILE
Ruben Pieters
Worked on Guardsquare/proguard-core, delivering three features over three months with a focus on maintainability and performance. Improved MethodLinker’s handling of long method chains, resulting in faster analysis for large codebases and providing clear upgrade guidance through detailed release notes. Managed release versioning by aligning code, Gradle properties, and documentation for the 9.1.11 release, supporting consistent downstream packaging. Refactored the Kotlin test suite from FreeSpec to BehaviorSpec, enhancing test readability and maintainability. Demonstrated skills in Kotlin, Gradle, and behavior-driven development, emphasizing commit traceability, structured documentation, and scalable test frameworks to support ongoing development and onboarding.
