Oli was born in Kg. Bauto, Telupid. His fascination with elephants began ever since he first saw them in 2014. He used to work at an oil palm estate in Kg. Bauto, in addition to tending his family's smallholding, but decided to join the Community Elephant Ranger Team under the Human Elephant Harmony Project. Now he spends time tracking the elephants' whereabouts in Telupid and collecting GIS data on their movement.
