Stavros focused on enhancing internationalization in the typst/typst repository by implementing a Modern Greek numbering system for document generation. Using Rust and backend development skills, Stavros updated the core numbering logic to replace archaic Greek symbols with modern equivalents, ensuring that generated documents align with current Greek conventions. The work included expanding and refining test coverage to validate the new logic and prevent future regressions, contributing to improved maintainability. Although the scope was limited to a single feature over one month, the changes addressed localization challenges and improved document fidelity for Greek users, reflecting careful attention to correctness and consistency.
