When Adda Birnir lost her job in 2008, she realised that her colleagues with information technology skills were not let go.

Two days later, she started to learn computer programming. She has since gone on to teach other women to code through a company she started.

The BBC explores what it takes to be a digital diva - and asks if it matters that men dominate the tech industry.

Produced by Anna Bressanin
