In June 2025, JBisi developed a Kotlin Enum Generation Mode option for the square/wire repository, introducing a new compiler flag to control how Kotlin enums are generated. By updating the WireCompiler API and implementing code generation logic in Java and Kotlin, JBisi enabled users to select between standard enum classes or sealed classes with data objects, enhancing flexibility for API design and interoperability. Comprehensive tests were added to validate the new mode across common Kotlin usage patterns. This work demonstrated depth in compiler development, API design, and testing, addressing configurability needs while maintaining compatibility with existing workflows in the project.
