As an entrepreneur, Roberto Santiago has started a few companies during the course of his career. After earning an undergraduate degree at the University Center of Joao Pessoa he founded his first company. This was a cartonnage company. He designed, manufactured, and delivered cardboard boxes to other companies that they used to package and display their products in.
Once Roberto Santiago had built up sufficient capital he purchased land in Joao Pessoa in order to develop a shopping mall on it. Manaira Shopping Mall opened for business in 1989 and it is the biggest mall in Paraiba, the state that Joao Pessoa is in, and among the biggest in Brazil. It took him two years to have this mall built. He serves as the chief executive officer of the company that manages this mall.
Over time Roberto Santiago has redesigned and expanded the mall in order to keep up with what people want out of a mall. The food court, for instance, is something that he has expanded three times. It has space for casual and fast food restaurants. It also has a new area that is for gourmet food and the first restaurant to occupy this space was the Capital Steak House.
Over time a gym was established at Manaira Shopping Mall. Roberto Santiago also enticed a college into being an occupant of the mall. It has a very large gaming area for entertainment (including a full bowling alley) as well as a modern theater that shows the latest movies.
One really popular expansion of Manaira Shopping Mall that Roberto Santiago had built was a rooftop concert space. This is called Domus Hall and it was completed in 2009. There is ample space to hold concerts in Domus Hall. It has also hosted many other cultural events like plays, conventions, fairs, exhibits. Additionally, high school graduation ceremonies have been held in Domus Hall along with a large number of weddings.
Roberto Santiago recently built another mall in another area of Joao Pessoa. This one is called Mangeira Shopping Mall and it opened its doors in 2013. While some people were concerned that the new mall would siphon sales and attention away from Manaira Shopping Mall, Roberto Santiago knew exactly what he was doing. Both malls are very successful and the opening of Mangeira Shopping Mall has had very little effect on Manaira Shopping Mall.
Roberto Santiago as an entrepreneur has greatly increased both the economic and social opportunities of the city he was born in. Other companies have decided to open locations around his malls including office space and retail stores. He took two areas of Joao Pessoa that needed a facelift and improved the lives of the people in the city.
