Yadanar Oo was born in Yangon in 1992. A computer arts graduate from the National University of Arts and Culture, she went on to study business administration at the Yangon Institute of Economics and spent several years working in marketing. Having come to the realisation that her true passion is filmmaking, in 2022 she decided to quit her steady job and apply for a place at Yangon Film School. Since then, she has worked on several YFS productions in different capacities including sound recordist (All We Need is a Little Breath, dir. Theint Mon Soe), sound designer (Dear Daughter, dir. Hsu Pan Naing) and colourist (With Love & Devotion, dir. Nant May Flower). She made her directorial debut with In the Heat of the Fire, a portrait of a similarly intense workplace at an iron foundry. Life is Salty is her second film.
