I have been developing games for 25 years. I participated in the development of Reel Online and led a team of 30 members to oversee the development of S4 League Online from start to launch, generating cumulative revenue of 50 billion won. Additionally, I founded Coco Soft as a one-person startup and developed Punch Hero with four developers, achieving 20 million downloads and 9 billion won in cumulative revenue. I also led a team of 30 developers to oversee the development of Boxing Star, which recorded 30 million downloads and 150 billion won in cumulative revenue.
