KRAFTON Cofathon FDE Track (Top 6)

I placed in the top six of KRAFTON's Cofathon FDE track at the PUBG Seongsu venue. KRAFTON hosted the event with CJ Olive Young as a domain partner and OpenAI as the technology partner. The track tested how quickly we could turn an unfamiliar operational problem into a working product.

In three hours, we worked through an esports team lead's requirements and built a voice interview simulator. Speech recognition transcribed answers, and speech synthesis delivered questions. The time limit included problem definition and interaction design as well as implementation, so choosing a small, complete interview flow mattered more than adding disconnected features.

Some model responses did not fit the workflow, so I separated the stages and checked intermediate outputs before continuing. We adjusted prompts and response handling, then validated a complete question-to-answer sequence. Reviewing my work alongside the winning solution afterward made the remaining gaps clearer. The experience reinforced how much software engineering fundamentals matter when the requirements and implementation have to move together.
