Worked on the foundry-rs/starknet-foundry repository, delivering a comprehensive refactor of the verify command to improve code organization and maintainability. The approach involved modularizing the command’s implementation by splitting it into subdirectories and introducing explorer and walnut verification interfaces, all while preserving existing behavior. This restructuring clarified interfaces and boundaries within the verification subsystem, enabling safer and faster future enhancements. The work was carried out using Rust and Python, with a focus on refactoring and command line interface development. The changes established a modular architecture that supports easier maintenance and extensibility, laying a solid foundation for future feature development.
