In pictures: Nigeria's repairmen

In a dusty, oily alley in the heart of Wuse market in Nigeria’s capital Abuja, 25-year-old Joshua Ejike sits with the guts of a flat screen TV in his lap.

"There's nothing we can't handle" he says. “LCD screens, DVDs anything.”

He came to the capital three years ago from rural Abia state after finishing secondary school.

He has never studied any technical or science subjects.
