Aristocrat Technologies Inc (ATI) 2008-presentAs a part-time contractor in video slot development, I have filled in the gaps for several teams which needed advice or development skills on quick notice. I have contributed to game platform software, many test and development aids, UI improvements for both games and operator menus, firmware and drivers for physical reels and related lighting equipment, software build automation, project management during critical test phases for complex games with complex collection of teams around the globe, recruitment of high-value talent, secure boot-time software validation, mathematical analysis and tools, etc. I contributed to the renewal of ATI's stepper product line (physical reels games, such as Alice in Wonderland, Zorro), and to several successful video slot game releases such as the series of Tarzan, Rockin' Olive, and Mission Impossible games, and the Crazy Taxi and Caribbean Treasure multi-player community games. Recently I've worked directly on game development such as Superman The Movie, Christmas Story, and some new stepper models, as well as game analysis and build tool suites.Since Aristocrat's 2014 acquisition of VGT, I have worked several cross-team projects to tie together the Class III (regular casino) and Class II (Indian bingo/slot games) markets and development teams, including tools to translate between the two markets, and for the Washington state video lottery market. Digital Dynamics Inc. 2005, 2009I integrated Digital Dynamics' SAS Engine protocol library into a customer's video slot platform code. Previously I worked on a protocol conversion tool for the then-industry-standard BOB protocol. C#, C++. Video Gaming Technologies (VGT) 2007-2008I created and updated Windows XP/embedded images for their video slot platforms, and worked on peripheral device drivers.

Intel Corp. 2011I developed a secure boot-time software validation process, using Intel's Trusted Platform Management (TPM) motherboard circuitry, standard BIOS, by customizing a standard Linux bootloader. PlyoSystems LLC 2008-2011Developed all software and performed systems integration and testing for a new piece of plyometric exercise equipment (the “PneuBounder”). This involved a user interface (controls and live feedback) on a ruggedized touchscreen device mounted on the handlebar (mostly in Lua), as well as the firmware in a platform-base-located circuit based on Microchip PIC, which monitored several sensors in real time (air pressure, acceleration, switches and air-valve controls) while running a physics model to calculate the athlete's power, force, usage, and communicating with the upper UI unit for athelete personalized settings, controls, and live feedback. This equipment is designed to improve athletes' jumping and sprinting abilities, with proper trainer involvement, and was used by the AF hockey team and local athletic clubs and trainers. Taeus International Corp. and IPEnginuity LLC 2007-2009Analyzed intellectual property (patents, etc) for validity and portfolio valuation, and tested devices for infringement, relating to optical storage media, software processes, database architecture, cellphone/radio, gaming machines. Tekvet Technologies, Inc. 2006-2008I wrote most of the firmware for two Microchip PIC-based circuits which transferred livestock health data (temperature) from their source at the radio ear tags to the central database server, for which I also wrote the original server software. Fisher-Price, Inc. 1998-2000I programmed microcontrollers for various musical, blinking toddler toys, including the original talking Rescue Heroes action figures. Profiles of Aspen, LLC 1986-1988I wrote patient database and data analysis software for a thoracic surgeon practice.

I was the development lead and architect for a new gaming device platform to support state-of-the-art industry concepts in a single gaming machine – any number of game types, game titles, money devices, screens, bonus devices, player input devices, etc. Based on .NET and written mostly in C#, embedded Windows OS's, hard drive storage, networked with the latest industry protocols to back-office systems, using USB devices where possible, this platform prototype impressed all analysts and customers at its 2004 debut, and drove new industry regulatory updates to handle the new technologies.Earlier work involved game title development (Popeye, Ray Charles' America, Hot Hot Hot, Super Bonus Poker, and many others), leading two game development teams, improvement of game development processes and tools for more reliable software production, secure boot-time software validation techniques and related digital signature tools, regulatory agency interaction and training, and general software process improvement.

Development Lead and prime software engineer for Air Support Operations Center software upgrades, designing and developing the UI, communications channels, database to help the Air Force support the ground troops. Ada, Java, C++, Solaris, HP-UX.

AF R&D projects including ISO layered demonstration model, later used for remote communication between AF bases . NORAD software maintenance, testing, and development team lead. C, C++, assembly; Unix and proprietary environments.Sole design and software engineer for the Battery Simulator portion of Rocketdyne's Space Station Power Engineering Lab, connecting to other simulators for power production (solar arrays) and charge/discharge control: circuit design, device control and real-time sensor simulation in software. Communication circuit switching for AF missile launch control centers. C/C++, assembly, Windows, Unix.In 1996, Lockheed Martin bought this part of Loral.

Circuit design, firmware, device drivers, software design and development for various Air Force, NSA, and related customers. Projects included multi-level secure message routers, investigation of optical parallel bus structures, communication circuit translators, test automation, development tools. Programming languages included various assembly languages, C, Fortran, Pascal in many development environments.In 1990, Loral bought Ford Aerospace.
