Paul Julius Nunda (born 12 September 1979), better known by his stage name Jua Cali, is a Kenyan rapper and record producer.

His single Kwaheri (featuring Sainapei Tande-winner Coca-Cola pop star and radio presenter) was a major hit in Kenya in 2007.

It also resembles Jua Kali, a Swahili term meaning fierce sun, which has been taken to refer to Kenya's informal sector of the economy.

Jua Cali is part of the Motorola family, and we are honoured to have worked with him in the recent past," says Joanne Doyle, the marketing manager for East Africa.

"He has been a great ambassador and, like Motorola, he is all about creativity, style and substance, so we could not be happier that his hard work has been recognised at the prestigious Kisima awards."

Juacali is arguably today's most successful artist in the Kenyan music scene as far as endorsements and pay per show income is concerned.

Early 2009, Telkom Kenya appointed him as the Orange Ambassador for their youth market and began his one-year sh10-million shilling contract by fronting the 'hello tunes' advertising campaign.

Players do not directly confront the threat of HIV; instead, they encounter challenges throughout the adventure that lead to lessons about risk and self-confidence.

The artiste has also been involved in other major advertisements such as Protex bath soap and Pilsner beer, and the deals have raked in big cash.
