Worked on the hiero-ledger/hiero-sdk-js repository to enhance the Transaction Layer by refactoring Client typedefs to use explicit channel generics. This approach replaced wildcard types with more precise TypeScript generics, improving type safety and code clarity throughout the codebase. The changes aimed to reduce ambiguity and lower the risk of runtime type errors in client integrations, while also laying the foundation for future generics-driven enhancements. Demonstrated strong skills in JavaScript, TypeScript, and type safety practices, with a focus on maintainability and onboarding efficiency. No bugs were fixed during this period, as the primary focus was on feature development and refactoring.
