My name is Marcos, I am 36 years old and for much of my life I have worked with math. When I wasn't building buildings and bridges, I was building systems for the Internet.When I was young, I lived abroad for 10 years, specifically in Switzerland, where I studied what in Brazil is called masonry, but in a much more advanced way. During the 10 years I studied there, I went to elementary school to finish high school and then entered a technical course in carpentry to become fluent in French. I studied for 4 years.Soon after becoming fluent enough to enter the "masonry" university, I enrolled in a degree at the University of Sion in Switzerland, where I went to the university once a week and 4 times a week to the construction site where I learned the practical part of the profession I was graduating in. I read projects and executed project tasks regardless of the size of the construction. My performance was so surprising that I soon became a construction foreman and delegated tasks and routines to my team.On Saturdays, I went to the same university to do a post-graduate degree where I learned German and mainly mathematical calculations in the geometry area to evolve to the architecture and engineering courses.As not everything is roses, after 8 years I had to return to Brazil, but as I mentioned, I have always been passionate about math, even in Switzerland I was enchanted by programming and, at dawn, on the way to work, I would read books on HTML, Javascript, and CSS and that's how I improved my English language.I learned PHP combined with the writing and reading skills of the English language through the documentation that I printed and used both to learn about the programming language and the language, I evolved in both simultaneously.In my 10 years of programming, I have worked with various types and sizes of systems, from commercial systems, to virtual stores and institutional websites, also doing work focused on the real estate, legal and human resources sectors, building systems for managing people.And this is a part of my professional biography.
