Developed and delivered an emoji-aware tag parsing feature for the usememos/memos Markdown parser, addressing the challenge of accurately handling emojis with variation selectors and zero-width joiners. This work involved implementing Unicode-aware parsing and string normalization in Go, ensuring that tags containing complex emoji sequences were no longer incorrectly split or truncated. By resolving a critical bug related to emoji truncation, the update improved tagging reliability and enhanced content discovery for emoji-rich posts. The project demonstrated strong backend development and testing skills, with careful management of production code changes through Git, resulting in more robust data quality and a smoother user experience.
