After graduating, he was invited by Songyos Sugmakanan to join the production of teen series Hormones as cinematographer. Hormones proved very popular and ran for three seasons (2013–2015), after which Pat was invited to co-direct GDH's comedy series Diary of Tootsies (2016) and also directed the TV documentary Let Me Grow (2016) for Siriraj Hospital's Psychiatry Department.^[3]

Following these works, Songyos and co-producer Kriangkrai Vachiratamporn invited Pat to take the lead director role for a segment of GDH's 2017 series Project S. He helmed the third segment, S.O.S, an exploration of major depressive disorder.
