πŸ“– Biography

Growing up in a Freetown neighbourhood where electricity arrived maybe once a week, Kelvin Doe began teaching himself electronics around age 10, scavenging scrap metal and discarded parts to repair radios and generators for his neighbours. At 13, calling himself "DJ Focus," he built his own FM transmitter, mixer and battery from acid, soda and scrap tin, and launched a community radio station broadcasting news and music from his bedroom.

In 2012, Sierra Leonean MIT student David Sengeh spotted Doe's talent through the Innovate Salone competition and brought him to the United States, where he became the youngest person ever admitted to MIT's Visiting Practitioner's Program.

Doe has since founded his own technology company and a foundation supporting young African inventors, continuing to build solar and battery solutions for communities without reliable power.
