Rochala worked on improving the reliability and maintainability of the Scala 3 compiler and the sbt/zinc incremental compiler, focusing on build configuration, dependency analysis, and documentation. In the scala/scala3 repository, Rochala stabilized flaky presentation compiler tests and corrected documentation to accurately reflect multi-parameter function desugaring, ensuring alignment between code and documentation. For sbt/zinc, Rochala enhanced incremental compilation by refining invalidation logic and optimizing transitive dependency handling, which reduced unnecessary recompilations and improved build performance. Using Scala and the Scala Build Tool (SBT), Rochala’s contributions addressed subtle issues in compiler internals, demonstrating depth in code refactoring and language design.

May 2025 monthly summary for scala/scala3 focusing on a docs-related desugaring issue and its alignment with code generation. Delivered a targeted fix ensuring documentation for multi-parameter function desugaring correctly reflects the actual transformation from def to val in generated code. This reduces developer confusion and support overhead, and improves reliability of the Scala 3 desugaring docs.

December 2024: Stabilized the scala3 presentation compiler test suite to enable reliable CI feedback and faster iteration for downstream features. The work focused on diagnosing flaky test execution, aligning test dependencies, and refining build configuration, including clarifying versioning comments to ensure reproducible builds and clearer maintenance paths. These changes reduce CI noise, improve release confidence, and support more robust Scala 3 compiler releases.
