    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.  less
