Worked on codebase maintenance and documentation enhancements for the lambdaclass/cairo_native repository, focusing on improving traceability and maintainability. Addressed technical debt by systematically linking all TODO comments to corresponding GitHub issues, enabling better tracking of outstanding work. Stabilized builds and runtime by implementing fixes in the Sierra Emu crate, and updated dependency management to align with current requirements, reducing potential risks. Enhanced documentation to provide clearer guidance for contributors and streamline onboarding. Utilized skills in Rust, Cairo, and compiler development to strengthen the reliability and clarity of critical components, supporting ongoing development and improving overall developer efficiency within the project.
