Tsz Wai Wu developed and maintained the MeshJS/mesh repository over 14 months, delivering robust blockchain infrastructure for Cardano applications. He engineered features such as transaction builders, coin selection strategies, and offline evaluators, focusing on reliability, modularity, and test coverage. Using TypeScript, Rust (via WASM), and JavaScript, he implemented secure cryptographic workflows, advanced serialization, and comprehensive error handling. His work included integrating APIs, refining fee calculation logic, and supporting smart contract execution. By aligning dependencies, improving test suites, and decoupling core modules, Tsz Wai Wu ensured the codebase remained maintainable, secure, and adaptable to evolving Cardano and SDK standards.
