United States - Last active: 3 months ago

Over the last 26 years, I have been deeply involved in all aspects of software development for a wide range of applications, including desktop applications (Java, C/C++, MFC, etc.), web sites (Java EE, HTML, CSS, Javascript, Perl, PHP, etc.), utility applications (Python scripts, Java command-line, etc), data visualizations, statistical packages, and more. Since 1996, my focus has been on Java, with a personal preference for command-line utilities and using Swing for desktop applications. Most of the open-source applications on my web site fall in one of these two categories (site URL given below). I've used too many tools and frameworks to list, but here is a sampling: Databases - JDBC, MySQL, PostgreSQL, Oracle, H2, Hibernate Build Systems - Ant, Maven, Gradle Continuous Integration - Jenkins / Hudson Source Versioning - CVS, Subversion, Git Testing - JUnit, TestNG, JBehave, Selenium Web Servers - Apache Tomcat, Jetty, JBoss, WebSphere IDEs - Eclipse, NetBeans Static Code Analyzers - FindBugs, PMD, Checkstyle, Sonar Misc - Lucene, Prefuse, OpenMap, JHotDraw, iText, SwingX, Apache POI I'll deliver clear, performant source code with full Javadocs and unit tests. I also have extensive writing experience; please see the "Publications" section below. I post some of my personal projects to my web site, as open-source. Please see the "Portfolio" section below. I am currently traveling in Asia and have a sporadic Internet connection. I'll post a video shortly after I return to the US on 21 Jan 2015.

Brazil - Last active: 12/29/2014 - Tests: 2

I'm thinking and playing with computers since I can remember. I’ve got my first computer when I was 12 years old. Luckily, this wasn’t a good computer this fact drove me through the programming world, because I spent my of my time coding small solutions just to have fun. Since them, I knew that I wanted to be a programmer for life. I took my first programming class when I was 14, finished my first college-level course with 16. In my last year in high school, I found a job to work building PDV software in a local company, but I resigned because I was dreaming about university. I started a Computer Science major in 2010, which opened my way to work in many fun projects. I helped to plan and build an online platform to connect hundreds of students and professors in order to help them to get founding for their projects. I also worked with investments, mobile apps, and many other small web applications. Until 2012 when I earned a scholarship to study abroad. In December 2012, I landed in Canada and had amazing 16 months, which I could study Computer Science at the University of Calgary, work as a summer student building new solutions for an Oil and Gas company, and I also had a blast connecting with people. I can tell from my past experiences that my greatest skill nowadays is to adapt and learn from new environments in order to solve any kind of problems. If you have a problem and you need help we can have a talk, I would love to help.
