    Good Day and thank you for taking a moment to read my profile! I started working in IT about four years ago as a technical support representative for Simple Helix, a Magento specialist web hosting company. From there, I had the opportunity to spend a year as a Network Analyst for a local, carrier class, ISP before moving on to a position as a Linux Systems Engineer with a Magento development firm. In the present, I work as an Applications Engineer with a focus on the TIBCO stack, most notably AMX, BusinessWorks, EMS, and Hawk. I've always felt that the only way to fully understand a system was to try to understand the systems around it. I've never been the kind of person who could tolerate only having knowledge of my particular area of expertise. I've got a very strong background in Linux/Unix administration and have worked extensively with CentOS, Red Hat, and Debian. I've worked with networks from a physical perspective, as a NOC Technican, as well as logical perspective troubleshooting complex application issues. Over the past few months I've taken the opportunity to learn to code in Java and I'm currently working on learning Python & Jython for an upcoming project. I'm a CPTE(Certified Penetration Testing Engineer) and would happily pursue projects as an E-Commerce Architect, Systems Engineer, entry-level Programmer, or entry-level Ethical Hacker.  less

    Overall , i have more than 15 years of development experience in multiple technical and human environment. For both start-ups and blue chip companies , i did contribute to the success of numerous projects , leveraging on my object oriented background , mainly in Java ( Swing , GWT , SmartGwt , Android ) Of course i am very knowledgeable in web technologies ( javascript / html / css ) and most of relational databases ( MySql , Oracle , SqlServer ..) , JPA persistence framework ( Hibernate ) Capable of communicating in English,French, and to some extent, German and Spanish , i am eager to take every challenge. As a developer , or as a lead developer, as i did before. Whether its about 'standard' web / mobile development , or advanced endeavor ( data mining , principal component analysis ) i am eager to take the challenge. Regards Keywords section for ODesk search ( If i type 'smartgwt' or 'SmartGwt' i don't get the same result so obviously search feature has a case sensitivity bug ) smartgwt About RESPONSIVENESS : I ALWAYS reply to requests EXCEPT SPAM. I got a 'Respond Rarely' evaluation from Odesk due to this. For instance i had more than 25 proposals from the same company which where either not matching my skills or well below my rate. I don't waste my time with this. If you ODesk guys read this , please implement a filter to reject proposals from some clients, or for proposals below a given rate. Thank you  less
