For the last ten years I have been working for major companies in the financial and telecommunication sectors. During this time I was involved in the following tasks: • Support Core Banking Services operating in various Application Servers (e.g. Oracle Application Server and Apache-Tomcat) under HP-UX (Service Guard), RedHat (HA Cluster) and Solaris 10 (Sun Cluster) • Deliver and design large scale virtualization (i.e. VMWare & HP Virtualization) infrastructures • Support and administer Warehouse infrastructure (i.e. Netezza & IBM Infosphere) • Consult and troubleshoot issues regarding SWIFT platforms and interfaces. • Analyse technical problems and create solutions involving the use of existing techniques and/or tools. • Perform assigned tasks in accordance with established standards and guidelines. • Prepare and recommend technical alternatives involving technology, methodology, tools, processes and solution components. • Installation, administration, troubleshooting of computer and network HW/SW systems

From missile defense systems (AMDWS) to simple LAMP driven web applications for over 10 years I have been working in the Open Source arena with a focus on Linux Systems and some Unix Based Systems (Solaris 10, FreeBSD). I have packaged for multiple Linux distributions, primarily RPM based, but do have some deb experience. For a brief period of time I ran my own Linux Distribution (Synergy Linux) to make in house servers easier to strip down and maintain for various pin point tasks (ie. NTP servers etc.) I am familiar with mock, koji and other Redhat distribution based imaging systems. I have had to edit and write with multiple scripting languages, bash, ruby (selenium), python, perl and even modified C and C++ patches to apply cleanly to new packages. I like a good challenge and to continue pushing myself to learn something new. I currently am working for a great employer as a Linux and Cisco Unified Call Manager Administrator, but I am in what I like to call maintenance mode. So I am looking for challenging side jobs to do in order to keep me on the cutting edge of opensource technologies. Also I don't mind doing remedial jobs just to earn a few extra dollars to further support my family. Depending on what other jobs I am currently doing I may be looking for a Linux support role, or just simply a data entry role I can write a script for. In either scenario I am excited to network and meet new people. Thank you for your consideration (and time in reading this). Kind Regards, Jeremiah
