Contributed to the ueberdosis/tiptap repository by developing a new autoTrim option for the CharacterCount extension, enabling manual trimming of text that exceeds character limits and providing users with greater control over content validation. The work involved TypeScript-based extension development and focused on maintainable, low-risk code changes. Additionally, enhanced the associated documentation in the ueberdosis/tiptap-docs repository by clearly explaining the new option and providing practical code examples in markdown, which improved developer onboarding and reduced potential misconfigurations. Collaborated with other contributors to ensure traceability between feature releases and documentation updates, demonstrating a methodical and detail-oriented engineering approach.
