Worked on the lightningkite/lightning-server repository to enhance the generation of TypeScript SDK type definitions, focusing on improving correctness and maintainability. Refactored the TypescriptSdk.kt file using Kotlin to properly handle nested types and implemented a deduplication strategy with a processed set, ensuring that duplicate type definitions were eliminated. This approach resulted in a cleaner and more accurate TypeScript SDK for downstream clients, reducing the risk of client-side type errors and simplifying future maintenance. Demonstrated skills in API development, backend development, and TypeScript generation, while laying the groundwork for broader improvements to the TypeScript SDK codebase.
