About me

Hi, I'm Hyun

I'm an American developer with a long-standing interest in Ukraine and Eastern Europe: its people, its history and its culture. I visited Ukraine in 2018, the Chornobyl Exclusion Zone included, and it stayed with me long after I came home.

I also love real-time strategy games. Frontline Zero is where the two meet: a game about how drones, jamming and reconnaissance have changed war, made with respect for the people living through it.
