    TIBCO Consultant & E-Commerce Architect

    United States - Last active: 1 day ago - Tests: 2 - Portfolio: 2

    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 SilverFabric. I have 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've recently attended Red Hat training for JBoss EAP 6. I'm a CPTE (Certified Penetration Testing Engineer) and would happily pursue projects as an E-Commerce Architect, Systems Engineer, TIBCO Engineer, JBoss Administrator, entry-level Programmer, or entry-level Ethical Hacker. I am available for new jobs immediately outside of US business hours.
