His first short film, Chicken Rice Mystery, was made in March 2008, just before he moved to Tokyo to continue his Masters (and later, a PhD) in Waseda University.

A few months later, Yeo made an experimental short, Fleeting Images, a homage to Sans Soleil by French director Chris Marker.

The short won the Grand Prix at the 6th CON-CAN Movie Festival in 2009 from an international jury headed by Japanese filmmaker Naomi Kawase.

He began rising to prominence in 2009 by writing and directing Love Suicides and Kingyo, two short films loosely adapted from the works of Yasunari Kawabata.

At the same year, he produced and edited Woo Ming Jin's Woman On Fire Looks For Water, which was also screened at the 66th Venice International Film Festival.

His 2020 film, Malu, is a Japanese-Malaysian co-production starring Malaysian and Japanese actors like Sherlyn Seo, MayJune Tan, Masatoshi Nagase and Kiko Mizuhara.
