Worked on the tvmlabs/tvm-sdk repository to deliver WebAssembly compatibility and performance improvements, focusing on enabling zk-enabled functionality for web deployment. The engineering approach involved refactoring Rust code to standardize wasm-friendly configurations, streamline code paths, and optimize build and binary size. Cryptography and dependency management were modernized by migrating to updated crypto libraries and refining workspace dependencies. Optional feature flags were introduced to gate ZK-related functionality and make API metadata configurable, while build profiles were tuned for web targets. The work simplified the HD key derivation API and ensured compatibility across WASM environments, preparing the codebase for broader web usage.
