The Nairobi Dev School equips youth in East Africa with computer programming skills and helps them build technology-based solutions to everyday challenges. The school was established in 2012 by Martha Chumo, a 21-year-old self-taught programmer, after she was denied a visa to study in the US. Chumo gave up a scholarship to study medicine after bumping into the tech world during an internship. When her attempts to refine her skills in the US failed, she decided to start her own school. The Nairobi Dev School has since conducted skills development training in Kenya, South Sudan and Somalia.
