Worked on the AdguardTeam/KnowledgeBase repository to enhance the accuracy and consistency of ad filtering documentation. Focused on correcting a typographical error in the create-own-filters.md file, replacing 'natches' with 'matches' across multiple language versions to ensure clear guidance for users. Utilized Markdown for documentation updates and applied careful attention to detail in typo correction, reinforcing the reliability of onboarding materials. The work addressed a specific bug, improving the quality of multilingual documentation and reducing potential confusion for both new and existing users. Demonstrated skills in documentation management and cross-locale consistency within a collaborative technical writing environment.
