Worked on enhancing the BoxLang compiler within the ortus-boxlang/BoxLang repository, focusing on improving stability and scalability for large-scale codebases. Addressed challenges with very large switch templates by implementing chunking logic to prevent recursive splitting of oversized methods, ensuring reliable compilation through targeted unit tests. Refactored flow-control handling to unwrap nested FlowControlResult values, which prevented internal sentinels from leaking into normal data and improved runtime data integrity. Expanded test coverage to include large switch scenarios and edge-case compilation paths, reducing the risk of regressions. Utilized Java, compiler design principles, and software engineering best practices throughout the development process.
