Kelvin Doe (born 26 October 1996 in Freetown), also known as DJ Focus, is a Sierra Leonean engineer. He is known for teaching himself engineering at the age of 13 and building his own radio station in Sierra Leone, where he plays music and broadcasts news under the name “DJ Focus.” He was one of the finalists in GMin’s Innovate Salone idea competition, in which Doe built a generator from scrap metals. Doe would constantly use discarded pieces of scrap to build transmitters, generators, and batteries, as well.
As a result of his accomplishment, he received an invitation to the United States and subsequently became the youngest person to participate in the “Visiting Practitioner’s Program” at MIT. His accomplishments were documented by @radical.media and presented on their corporate YouTube channel. When the video went viral, the story was picked up by CNN, NBC News, and The Huffington Post.
Doe subsequently was a speaker at TEDxTeen and lectured to undergraduate engineering students at Harvard College. In May 2013, Doe signed a $100,000 solar project pact with Canadian High Speed Service Provider Sierra WiFi.
