Contributed to the nvaccess/nvda repository by expanding the Slovak Language Symbols Dictionary, enhancing text processing accuracy for Slovak-speaking users. Focused on internationalization and localization, the work involved updating the dictionary to support a broader range of characters and diacritics, ensuring improved accessibility and readiness for future language features. The update was carefully aligned with the 2025.2 release cycle to maintain compatibility across NVDA core and related components. Demonstrated technical skills in Unicode handling, dictionary-based symbol management, and Python development, resulting in a more robust foundation for Slovak language support and better localization practices within the project.
