Interested in multimedia platforms for 3D virtual worlds and applications which require 3D rendering/modeling resources. Hardware interfaces of interest include the Cyberith gaming platform, the Oculus Rift, the PrioVR system (17 sensor Pro Developer Suit), and the Leap Motion VR developer tools. Unity 3D and the Unreal gaming engine are also areas of recent study. Java multimedia applications are interest, especially those which use advanced 3D modeling/rendering technologies. Java technologies of interest include J2SE, J2ME, Java3D, JINI, JMF, Android, & JavaFX. Currently using Xcode, Eclipse, Atmel Studio, Qt, and Netbeans IDEs for development. I develop virtual world content and software for HighFidelity.io, Second Life, and OpenSim. I recently installed source code for the HighFidelity project and plan to get more involved in related development projects. I have experience building and configuring OpenSim servers on Ubuntu Linux, Mac OS-X, & Windows platforms. I am also interested in porting OpenSim to ARM based platforms. My VR servers are currently running on Via Technologies Mini-ITX cards and Nvidia Jetson cards. My focus is to develop a small VR appliance (VRMAD) that includes preconfigured environments that require very little configuration input from the end users. Leveraging embedded Java solutions using chips from aJile Systems, Yost Labs, Nvidia, and Imsys Technologies.I have extensive experience porting applications to Mac OS-X, Windows, and various Linux platforms. My broad exposure to operating systems includes; Mac OS-X, Fedora, Ubuntu, Mint, CentOS, Android, Chrome OS, Solaris 10. I typically use Java, C, C++, and some TCL/TK & Qt for development projects. Considering Swift for iOS applications.

Hardware & Software Engineer - Embedded Design For Vr/Ar ApplicationsEpicenter Technologies - Engineering Services Feb 2019 - PresentPursuing AR/VR/IoT development projects.See samples of my virtual worlds on Sansar.com (Drifter's Desire) or Opensim based projects on OSGrid (Regions: Banshee Cove or Epicenter Technologies). I design custom VR worlds on Second Life, Opensim, Sansar, and High Fidelity. In addition to virtual world design, I am also developing a new VR hardware platform and a library of software APIs for Nvidia Jetson TX2 cards. Several VR related peripherals and hardware interfaces are in development now. The intent is to develop interfaces that allow you to control real world devices from within a virtual space. IoT devices with a VR spin!

Sr. EngineerLexmark International Mar 2005 - Aug 2011Lexington, Kentucky, UsWas a senior engineer responsible for device/process modeling, process characterization, standard cell development, and CMOS design methodologies. Used BSIM Pro for semiconductor device modeling and Cadence VSDE/VCME for timing characterization. Developed the CMOS standard cell family that was being used for ink jet print head development. The cells were compatible with the Cadence Encounter place and route system and support Synopsys and Xilinx flows for synthesis. The cells were also ported to the Tanner place and route tools. Used the Coventor SEMulator3D tools for device structure and standard cell analysis. Participated in RCX/QRC correlation activities using parasitic extraction structures and various circuits for digital performance analysis. Was also responsible for parametric process analysis and monitoring using Spotfire/JMP data analysis software, ChipCentric, and custom Process Control Monitor structures. The group I worked in was part of the Lexmark Imaging Solutions and Services R&D Group which was responsible for new ink jet print head designs and systems. -
FounderVrmad 3D Multimedia Platform - Epicenter Technologies Mar 2002 - Jun 2004Designed a Java based broadband multimedia VR platform and teamed with five partners to pursue venture capital funding for the project. Developed the business plan, product specifications, technical presentations, and marketing support material. Conducted research on product components, Java processors, software APIs, manufacturing resources, and competing technologies. Developed and submitted patent applications and support material as needed. Made the hardware architecture for the VR platform public after development funds were exhausted.

Semiconductor Device Modeling EngineerLevel One Communications Aug 1987 - Jul 1990UsEmployed as a Device Modeling Engineer developing circuit simulation models for CMOS and BIPOLAR devices. Modeling activities were supported by IEEE-488 software driving parametric test equipment from a Vax 11/780 and a Macintosh II. I was responsible for the definition and development of the entire system including low level hardware interfaces. Semiconductor characterization routines were developed using LabView instrument control software and Lightspeed C. Statistical process control databases were implemented on the Macintosh and were used to determine the upper and lower bounds for various device models. Parameter optimization algorithms were used to fit the models to empirical data. -
