    Carlos Gilberto Martínez Martínez

    Enthusiastic Java Senior Developer

    Colombia - Tests: 4

    My experience focuses on developing mobile, web and desktop Java applications which gives me a wide range of Java platforms experience: I worked for 19 months in big desktop and web Java projects for 'Media Interactive', an international development company located in Kiel, Germany. I was in charge of designing and coding software modules oriented to the airline industry. During this period I became a Senior Developer and Team Leader. For Media Interactive, I developed software by using the Swing framework for JSE, and the Tapestry framework for JEE. Structs and Hibernate were used for data persistence and communication with ORACLE databases in those projects. I have experience in written and audio-visual communications with developers, QA members and project managers using English as a common language. Through the 'Jira' platform and Skype I could participate in a collaborative development environment. I have used XML a lot by using Tapestry and also when writing android apps, which is one of my favorite platforms for my free time by the way. I have developed for JME and BlackBerry in my free time as well. I have a little experience in JavaFX, PHP, and the old starter C++. Off course I remember those charming days when I used MySQL. I'm looking forward to learn a lot by participating in challenging cross-platform projects, improve my developing, leading and human interaction skills while getting to know exciting and experienced software-related teams.
