    Over the last 5 years I have developed a wide range of applications. Some for the companies I have worked, some for freelance jobs and some for national competitions. I have developed web interface with ExtJs for Turkcell (the biggest GSM company in Turkey and East Europe and Mesopotamia area). I developed a J2EE project called "GSM Based Remote Monitoring and Billing" and became the winner of the IBM software competition in 2009. You can see the details at http://www.yazilimakademisi.org/2009/. (It is in Turkish. Sorry.) I have worked for Sun Microsystems before they acquired by Oracle. I worked with them for six moths as a campus ambassador. Last year I worked with a SAP Consulting company. I used Java, Gwt, Gxt, Vaadin and mysql in there. Also I developed a company portal for their internal usage with PHP, Ajax and Mysql.  less

    If it's procedural it can be taken care of with fluid programming and if it's data - well, it can be warehoused. I have been programming with Visual Basic and building databases with MS Access for 4 years now. What began as a need for more rows in a spreadsheet led inevitably to complicated import routines designed to parse, validate, and, store data. Well laid out user interfaces came next, allowing even the most inexperienced user to safely navigate the database with no risk of compromise to the data. Finally, heavily customized reports were laid out to put the data to good use. I have designed several databases for a variety of applications primarily within the Mining industry. I feel my strengths are best seen in the design of the user interfaces used to manipulate the applications I design followed closely by data imports and report writing. I've recently branched out to larger database systems, utilizing SQL Server as an access managed back end. When VB isn't enough, I resort to writing utility scripts in Python or DOS based batch files to take care of little chores.  less

    LinkedIn http://www.linkedin.com/in/jmdots Summary I've worked in technical administration, technical support, customer service or leadership roles for all but a few months of my adult life. In this time, I climbed the ranks of a highly-modern, lightning-paced, large-scale, multi-OS supercomputing environment in Area B of Wright-Patterson Air Force Base (WPAFB) and became an avid user of all things open source. The place which was my professional home of over six years is known as the “Air Force Research Laboratory DoD Supercomputing Resource Center” or "AFRL DSRC" for short. The AFRL DSRC environment is home to the #19 supercomputer on the June 2011 Top500 Supercomputer List, a mammoth computer for which I received training: Cray Inc.'s "Raptor" XE6.
