Wicked Local WESTFORD -- Business owner Ruth Agbjai describes herself as "CEO and nerd-in-chief" at Code Wiz, which offers after-school programming in high-tech skills for children ages 7-17. An immigrant from Nigeria, Agbaji, now a Boxborough resident, understands the experience of the outsider. That, she said, is how children with a zest for computers and technology sometimes feel -- and part of what drove her to open her Westford-based business, Code Wiz. "To put it very simply, our mission is to help kids unlock their potential through coding and robotics," said Agbaji. "We all have it in us to be able to learn."
