Backgroud
Today I am systems analyst at CDIS, a business unit of ISG Group, a multinational company headquartered in Brasilia/Brazil. I am part of the development team of Brisk PPM, the main product of the company, working in Front-end and Back-end development, database and information security. I've been in the company since the end of 2017.
I have been a collaborator at Dyress Corp since mid-2018, working on the development of the Dyress platform, a cloud service based on Artificial intelligence, unique in the world.
Since 2016 I am a collaborator and partner of "Catalogo das Artes" website, considered the largest portal of arts, antiques and collectibles in Brazil.
I have as a personal project the Altweb, an initiative that obtained 2nd place in an innovation contest of the ISG group.
In 2015, I have developed "Comex Global", an alternative tool for Brazilian foreign Trade database (known as AliceWeb).
Development of "Clube Fitness", a fitness app created in 2014 in partnership with Fitclub Fitness Academy located in Brasilia. The app simulates a gym workout sheet based on artificial intelligence without the help of a teacher
At the end of 2009 and until 2012, I developed Amithings, an IOT experiment based on 7 principles that established a new model of information storage, reducing the impact of duplicity of information on the web and allowing total granularity in access to Information.
From 2008 to 2009, I had the opportunity to work on an ambitious and innovative educational project, the "Gerenciamento de Estudos", based on the theory of tests, from a diagnosis of the student, elaborates a study plan aimed at the application of exams, competitions and tests. The project was sold to a large company in the educational area of Brasilia.
In 2007, I founded "Suporte On", an IT startup. The company provided consulting services in ICT, having worked with several clients and partners in Brazil, performing activities such as software development, intranets, Internet, information security consulting and online communication. The company has developed innovative projects such as Amithings, Clube Fitness and Comex Global. "Suporte On" ended its activities at the end of 2017.
In 2006, I created "Generator", a rapid generator of intranets, websites and Web applications from pre-existing databases. Working as a wizard, the software obtained information from an Access, MySQL, SQL Server or Oracle database and generated ready-to-use screens, with a reasonable degree of sophistication, contemplating the basic functions of an Intranet application, including the Report generation. Generator had the ability to generate source code in ASP Classic and PHP. This product motivated the creation of the "Suporte On" startup.
