WORK HISTORY

January 2007-April 2008, consultant, ASC Signal (formerly a division of Andrew Corporation), Richardson, Texas

This project involved software for the monitor and control of satellite earth stations. The client sides were in VC++ and C#. The server sides were VC++ and C. The OS’s were Windows and Linux. Communication on the C# project used SNMP, TCP/IP, FTP, and .NET Remoting. The development systems were Microsoft Visual Studio and Eclipse. My work involved everything from Windows GUI’s to Linux device drivers.

December 2006, consultant, Newsom Terry & Newsom, Dallas, Texas

This project involved retriving stock data from a website and loading it into an Excel spreadsheet.

December 2005- December 2006, consultant, Via Nova, Dallas, Texas

This project involved using 3D graphics for training purposes. This application provides the user with a virtual reality environment and provides feedback on their actions. I did all aspects of this project and used Windows for the O/S, C# for the language, PostgreSQL as the database, Direct3D (Directx 3D) as an API, Blender as the 3D modeling application, Microsoft DirectX3D Framework, and Ogre 3D as the 3D engine. Some experience with OSG (Open Scene Graph) and Irrlich 3D engines.

September 2005- November 2005, consultant, Wavetrix, Richardson, Texas

Embedded microprocessor RFID (Radio Frequency ID) project involving wireless communication and remote sensoring systems. Microprocessors would communicate with each other using a Chipcon Zigbee wireless communications chip. I did device drivers and other microprocessor code. I also did a test PC application controlling these microprocessors over a TCP Internet connection. The development system was a NetBurner Motorola Coldfire 5272 with uC/OS RTOS.

November 2000-August 2005, consultant, AMCI, Dallas, Texas

Client-server application for sales reps to place orders. Used Internet socket communications to communicate from client to server. I did every aspect of software development for the full life-cycle of this project. The database on the client and server was designed by me.

The client application was written in VC++ and allowed the sales rep to create and upload orders to the server. The application would give the sales rep catalog items to choose from in creating an order. The sales rep could also run reports on the database. Data access was by DAO with an Access database. Sales reps could print barcodes as well as read barcodes to input orders. Orders could be faxed, emailed, or uploaded to the server. Emailing involved using Office Automation of Outlook. Excle spreadsheets could be imported using Office Automation of Excel. Work on the client side was ongoing during the entire consulting time for AMCI.

The server application was written in VC++ and allowed the operators to import catalogs, customers, and vendor lists. The operators could also modify things like catalogs using an editor. The operators could also run reports on the database. Data access was by ADO with a SQL Server database. Orders could be faxed, emailed, converted to an Excel spreadsheet or printed. Emailing involved using Office Automation of Outlook. Excle spreadsheets could be imported and exported using Office Automation of Excel. Work on the server side was ongoing during the entire consulting time for AMCI.

A few ASP (Active Server Page) web apps were written in C#. One app allowed a vendor to confirm the receipt of an order by simply clicking a link in an order email. Other apps allowed operators to edit orders in the SQL Server database from the internet. The work on C# ASP web apps was around 6 months.

January 1997- December 2000 consultant, Via Nova, Dallas, Texas

Designed and wrote a screen-saver for Windows using Visual C++, MFC, and the OpenGL 3D graphics rendering package. It was a simple 3D modeler that allowed the user to create complex 3D objects from 3D primitives. The user could also use a Wizard to configure some of the displayed screens with personal information. The 3D modeler had the ability to apply textures, control lighting, do animation, and do 3D text with special effects such as shadows and embossing.

April 1997-May 1997, consultant, Infopoint Systems, Richardson, Texas

Maintanence, in a team environment, on Windows 95 application using Visual C++, MFC. Also configured Install package. These were minor changes requested by the designers of the software.

Responsible for all the development on a Windows 95 VxD's using Visual C++ and the Vireo VToolsD development system. File system hook and device driver. This software made a CD appear to be a writable device. It picked off write requests to a CD and transferred them to a RAM disk.

May 1996-June 1996, consultant, Infopoint Systems, Richardson, Texas

Developed Windows 3.1 application, in a team environment, using Visual C++, MFC.

August 1994-April 1996, consultant, Via Nova, Dallas, Texas

Designed and wrote a screen-saver for Windows using Visual C++, MFC, and the OpenGL 3D graphics rendering package. It was a simple 3D modeler that allowed the user to create complex 3D objects from 3D primitives. The user could also use a Wizard to configure some of the displayed screens with personal information. The 3D modeler had the ability to apply textures, control lighting, do animation, and do 3D text with special effects such as shadows and embossing.
