He quickly established himself by directing a wide array of short films, commercials, and popular music videos, including hits like Palmy's 'Duang Jai," STAMP's '1%,' Whal & Dolph's 'Skyfall." and INK WARUNTHORN's 'Erase.' This diverse experience laid the foundation for his venture into feature filmmaking.
