Worked on MystenLabs/ts-sdks over a two-month period, focusing on stability and reliability improvements in front end systems using React and TypeScript. Addressed server-side rendering issues in wallet components by implementing isomorphic layout effects, ensuring consistent behavior between client and server environments and improving wallet flow reliability. Further enhanced the codebase by refactoring the encodeQuilt function to prevent in-place mutation of the blobs array, thereby preserving data integrity and improving determinism in the encoding pipeline. The work emphasized maintainability and correctness, laying a solid foundation for future feature development while prioritizing robust engineering practices in JavaScript and TypeScript.
