Profile

I started my career at the age of 14 in the gaming industry in Brazil, working with electronics and game programming.

Experience with these programming languages: PHP (10 years), HTML5/Javascript/JQuery/CSS (15 years), Python (3 years), C# (2 years), VB.NET (3 years), VB6 (10 years), ASP Classic (15 years).

I have worked as a security consultant for medium-sized companies in Brazil. My work was focused in web application security, having developed my own tools and techniques along with a set of wordlists for specific languages and purposes. I have experience with Kali Linux and its tools, BurpSuite, Metasploit and a large number of security tools from the community.

I am SQL Server Database Administrator, having worked with it since 2000, working with T-SQL programming and server administration. I am specialized in database performance, working as a consultant for some companies in Brazil.

I have knowledge in Oracle databases since 8i version, working with development of VB6/Oracle applications and PL/SQL, and I have 5 years of experience with MySQL database.

I am a Windows Server Administrator, with experience in installation and configuration of this OS (Active Directory, Firewall, IIS, DHCP, DNS, LDAP, File Server).

Backgroud

I have been worked as Systems Analyst at CDIS, a business unit of ISG Group, a multinational company headquartered in Brasilia/Brazil. I was 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 from December 2017 to January 2020.

I was a collaborator at Dyress Corp from June 2018 to February 2019, having worked on the development of the Dyress platform, a cloud service based on Artificial intelligence.

From 2016 to 2019, I was 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.
