Mr Dadzie started Rancard Solutions in 2001
It was in the late 1990s. He was in the United States, studying at Vanderbilt University in Nashville, Tennessee, and after a summer internship he started to reconsider his dream of becoming a mechanical engineer.
On second thoughts, he decided to get a degree in computer engineering instead.
“I was just very excited about what I felt that could be done back home,” he told the BBC’s series African Dream.
Today the company that he started in 2001 with his business partner Ehizogie Binitie, Rancard Solutions Ltd, is considered one of the leading IT firms in West Africa.
Last year, Rancard Solutions was selected as one of the top 15 companies of the continent during the Africa Awards for Entrepreneurship, out of 3,300 candidates.
The firm has now offices in Ghana and Nigeria and mobile service delivery in 32 markets in Africa, the Middle East and Asia.
It develops software and services that clients such as Vodafone, Tigo, Google and Voice of America use to communicate with mobile phone users.
