Architecting and reconstructing Lumina Debating, upgrading and optimizing the AI agent system for higher performance and seamless processing.
Featured Work: Lumina Debating
Back in high school, I was able to speak English but faced difficulties in explaining and clearly transmitting my ideas during conversations. Over time, I realized that being able to narrate things clearly and robustly, and debating perspectives with others in English, is a powerful skill.
At first, I built this app just as a portfolio project, never thinking it would work well for anyone—even myself. However, I soon met classmates and friends who faced the same pain point. I invited them to test it, and they said:
“Although your web looks ugly, it is really effective in enhancing my English speaking and narrating skills.”
This feedback drove me to reconstruct Lumina into a better web application, as I believe it can play an important role in addressing this exact speaking and narration pain point.
