WORK HISTORY:

Confidential, Dallas

Responsibilities:

• Developed 3D graphics application for training purposes.
• This application provides the user with a virtual reality environment and provides feedback on their actions. Did all aspects of this project and used C# for the language, PostgreSQL as the database, OpenSceneGraph (Open Scene Graph, OSG) as a 3D API, Blender as the 3D modeling application.
• Some experience with Direct3D (Directx 3D), Ogre 3D, and Irrlich 3D engines.

Confidential, Richardson, Texas

Responsibilities:

• Wrote embedded software for the monitor and control of satellite earth stations.
• The Windows client sides were in VC++ and C#.
• The Linux server sides were VC++ and C++.
• 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.

Confidential, Richardson, Texas

Responsibilities:

• Embedded microprocessor Confidential project involving wireless communication and remote sensoring systems.
• Microprocessors would communicate with each other using a Confidential wireless communications chip.
• Wrote C++ device drivers and other microprocessor code.
• Also developed 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.

Confidential, Dallas, Texas

Responsibilities:

• Client-server application in VC++.
• Used Internet socket communications to communicate from client to server.
• Did every aspect of software development for the full life-cycle of this project.
• Designed the database on the client and server.
• Data access was by ADO with a SQL Server database.
• A few ASP (Active Server Page) web apps were written in C#.

Confidential

Software engineer

Responsibilities:

• Created and maintained microcode and test applications for a 3D graphics processor utilizing bit-slice processors in a pipeline architecture in a team environment.
• Wrote assembly language for another 3D graphics processor based on microprocessors.
• These processors would traverse a 3D scene that was prepared by a user application.
• The processor would do transformations, rasterizations and do picking of elements in the 3D scene.
• Wrote assembly language for a LAN (Local Area Network) communications controller and intelligent terminals
• Wrote software for a multi-tasking operating system that controlled a voice authentication security system.
• I managed product life cycle including initial product specification, design, creation of software standards, scheduling of tasks, implementation, testing, and customer acceptance, training, and support.
• Designed and wrote software implementing HDLC over a 1 Megabit/Second communications link.
• Designed and wrote disk controller S/W, file system, and SCSI interface to a disk and tape drive.
• Interface routines for UART, timers, clock, DMA, floppy controllers, hard drive controller, communications controllers.
• Hardware diagnostic systems. TTY based Unix-like Shell interface with interface routines, and command processors.
• Configuration and programming for VRTX real-time multitasking operating system.
• Wrote device drivers and tasks using interprocessor communication. System maintenance of Unix O/S. Routines for operator to test hardware.
