Gongko King developed a daily progress logging feature for the IntensiveCoLearning/english_2nd repository, focusing on tracking Duolingo user engagement. By updating Markdown documentation files such as Chacha&Qi.md and Qi.md, Gongko established a clear record of user activity and consecutive streaks for October 25–27. The approach relied on precise documentation practices and git-based change traceability, ensuring that progress data was both transparent and auditable. This work laid a foundation for future analytics and gamification metrics by providing structured, lightweight data-logging patterns. While the scope was limited to documentation, the implementation demonstrated careful coordination and attention to data integrity.
