Contributed to the JetBrains/kotlin-compiler-server repository by developing a new suite of Kotlin test samples that demonstrate core language features such as basic syntax, control flow, lambdas with receivers, scope functions, object declarations, and array handling. The work involved creating sample code files and updating existing tests to integrate workaround files, ensuring compatibility and accurate validation of the new samples. Focused on enhancing test coverage and maintainability, the developer applied skills in Kotlin, sample code development, and testing. These updates strengthened quality assurance for the Kotlin compiler-server, aligning test coverage with recent language enhancements during the 2025-08 development cycle.
