Worked on the Kotlin/kotlin-lsp repository to deliver enhancements for template handling within the Language Server Protocol, focusing on range-based modification templates and automated post-template actions. Developed features that allow templates to be applied precisely within specified element ranges, introducing a new overload in the FakeModPsiUpdater for granular control. Enabled automatic actions to occur after template creation through psiUpdate, streamlining template-driven workflows and reducing manual intervention. Utilized Kotlin and Java to implement these improvements, demonstrating expertise in code generation and IDE development. The work concentrated on robust feature delivery, with no major bugs reported, reinforcing maintainability for downstream tooling.
