Worked on the multiversx/mx-sdk-rs repository, delivering targeted improvements in Rust over a two-month period. Developed a static TLS deployment enhancement by introducing a new Cargo feature, enabling static TLS for both framework and SDK HTTP crates and updating dependencies to support secure deployment scenarios. Additionally, addressed reliability in the event system by refining macro logic to ensure every event receives a valid identifier, using the method name as a fallback when necessary. This macro-level change improved event handling robustness and reduced runtime errors. Demonstrated skills in Rust, macro development, event handling, and SDK development while maintaining clear documentation and test coverage.
