Professional References
Mariana was one of the most creative and passionate individuals I met. As an intern in the sales and marketing department of Buslead project, she demonstrated her imagination and creativity helping us to brainstorm ideas, creating a sketch of the company's advertisement and helping to develop the brand identity of the company. She is definitely not a person to do repetitive tasks, cold calling or administration - she is too energetic and passionate to kill it with office jobs. She is definitely THE person when it comes to marketing, communication, event management or relations management. She is very sociable, cheerful and talkative and can easily connect to any audience.
