She then transferred to Kyebambe Girls' Secondary School, in the city of Fort Portal, where she completed her O-Level education.

She started as an unpaid volunteer/intern, and was later employed as a weekday morning show co-host at NBS Television with Shawn Kimuli, broadcasting at the network's headquarters in Uganda's capital city, Kampala.

She was selected as the East African Reporter for Deutsche Welle (DW) covering environmental issues and exciting solutions from Africa and Europe, serving in that role until October 2017.

[12][13][14] The next day, Biira, who was in her hometown of Kasese, for her wedding to fiancé (now husband), Newton Kung'u, a Kenyan citizen, was arrested by the Uganda Police, because she had posted photographs and a video of the inferno, after the attack, on some of her social media pages.

Arrested and charged for the theft was one Aaron Obudho Ochieng, an editor at the television station where he and Biira worked.
