Engineer skilled at developing and testing hardware used in mission-critical Windows 7 Pro, Windows Embedded, and Windows Server 2003 & 2008 based systems for industrial and commercial systems.
EMPLOYMENT HISTORY
Software Engineer
Spectrum Technologies, Inc. – Aurora IL – December 2012 to June 2013
Contract programmer .Net C# and VB6. Expanded functionality of primary corporate software package by providing support for new products. Developed new software plan for a software application interfacing the company’s weather station to be teamed with a nationally recognized golf course irrigation company's application.
Project Engineer
Scalar USA – Thermal & Electronic Testing – Rolling Meadows IL – February 2012 to August 2012
Contracted to develop a new line of hardware testing business for McDonalds vendor, Scalar USA. The company performs evaluation, remediation and certification testing of potential and released systems' suitability for use in stores located in all world markets.
As a part of the initial contract negotiation with McDonalds, applicant produced a favorably received thermal map analysis of two devices for McDonalds. One device was a potential prototype, the other was a unit already in production and being used in stores world-wide. Recommendations to McDonalds included small heat sinks to be added to integrated circuits at risk of early failure due to their high normal operating temperatures and the typical temperatures found in most grill kitchens.
Designed and built thermal test chamber and electronic control system.
Designed a test plan using a commercial test chamber that would simultaneously control for thermal and electrical testing as the DUT (device under test) experiences thermal and electrical stress. Test plan included creating a thermal profile of a typical McDonalds restaurant food preparation and grilling areas of store. This thermal profile would be used as the baseline operating temperature range for tests that would add electrical stress events to evaluate the DUT as possible standard equipment in the stores.
Created a Windows 7 Embedded Standard operating system image for a 64 bit tested prototype device in a proof of concept test. Created script to “exercise” the Windows 7 Embedded OS image at varying levels of stress on specific hardware devices. Operating system image was compared with the standard McDonalds Windows XP Embedded operating system used in other similar devices.
Performed, documented and published an open source thermal study of the Raspberry Pi, a Linux based, credit-card size, inexpensive home computer used to teach programming to middle and high school students world-wide.
System Engineer / Analyst
RADI LLC – Retail POS software – Oak Brook IL – May 2011 to December 2011
Providing technical support for new features, customization and software maintenance on a point-of-sale proprietary software system used in 33,000+ McDonalds stores in the United States. Customization language is JavaScript operating as standalone modules and as components in a specialized IIS web based system. Software patches were managed using Subversion, Beyond Compare and Visual Studio 2005. Did tests on the application using Oracle VirtualBox. Built release packages using Wise Package Studio.
System Engineer / Lab Manager
RADI LLC – Retail software – Oak Brook IL – August 2010 to May 2011
Installed, maintained and repaired 25 QA test setups operated as fully functional McDonalds store simulators. A typical store simulator included: 2 Windows 2003 or 2008 Servers, 6 - 8 Windows XP Pro POS registers (Point of Sale cash registers), 4 to 8 Windows XP Embedded low power CPUs used for data display. IIS 6 delivering ASP pages was the Admin configuration interface. Configuration testing required modifying IIS web server setups, user accounts and embedded scripts using VB and JavaScript.
Managed special store and computer configurations with VB scripts using WMI and VB objects.
Provided training and hardware test support to test contractors working in as Quality Assurance and Business Analysts, testing operating systems and application software used on all McDonalds store computers.
Systems Engineer / Hardware & Software
Pason Inc. (bought out Petron) – Oil & Gas Exploration – Houston, TX -- October 2009 to August 2010
Petron Industries Inc – Oil & Gas Exploration – Houston, TX – May 2001 to October 2009
Designed and developed twelve computer product lines to support over $15 million in annual oilfield business. Created custom Windows XP Pro system images running the company's specialized application software used to display oil well operational parameters. These systems ran in various office spaces on both land and off-shore drilling rigs. It was the industry leading standard equipment for independent drilling companies.
Created a series of four different touch-screen enabled HMI operator systems based on Windows XP Embedded operating systems for use on the drilling rig floor by oilfield personnel in hazardous environments. The touch screen systems were featured for 7 years in the Petron booth at the Offshore Technology Conference, the largest annual oil industry convention in the world. Successful operation required less than 10 minutes of training to use. Generally the system did not require a keyboard or mouse to be attached. Systems were successfully installed on hundreds of land and off-shore oil rigs worldwide for nearly ten years. Most of the off-shore systems are likely still operating.
Designed and tested for deployment a PLC interfaced Hall-effect flow sensor for draw-works cooling water.
Designed the deadline hook-load strain gauge sensor system used at The Mudlogging Company and it brought me to the attention of management at Petron. A similar system was created for Petron.
Developed a 4-20mA strain gauge flow-paddle sensor.
Designed and built PLC/PCN systems used for auxiliary data displays and metering used in the driller's cabin on a number of off-shore oil rigs now stationed in the North Atlantic, off the coast of north Africa and offshore in the South China Sea. PCN software in the PLCs communicated using ModBus Plus via fiber optic Ethernet.
Standard TCP/IP networking for the computers was also implemented using fiber optic multi-mode 100FX networks allowing the rig monitoring computers to remain functional even during cracking operations.
Created intrinsically-safe HMI electronic hardware interfaces circuitry and printed circuit boards used in many of the company's product lines. These interfaces isolated the serial RS485 network for data acquisition, the copper Ethernet system at 100Mb/sec, an alarm horn and an isolated power switch. Circuitry created was incorporated into future models of the Computer Dynamics Wolverine and Wolverine II computers in a technology deal.
Performed on-site installation and testing of custom and prototype computer and PLC systems.
Tested thermal, electronic and intrinsic safety parameters of computer and peripheral systems for use in the corporate product line.
Validated vendor claims and tested for extended temperature range operation using cooling systems for those systems delivered to drilli...
