Hello! Okay I'm not sure if this position would be suitable for a game jam but I'm a newbie translator looking for projects!
I could do English -> Thai and vice versa. I've got 6.5 IELST from about 4 years ago and 960 TOEIC from about 2 years ago. I also spent 3 years studying high school in New Zealand. As for Thai proficiency, I'm a native speaker.
Even if working in a game jam with tight schedule wasn't suitable, I still hope I could help translating your game afterwards!
