Migrated control code for all the engine test stands from LabVIEW to a proprietary scripting language for SpaceX. This involved aiding in the development of new commands using OOP structures in LabVIEW. Worked with a team of developers using SVN and a JIRA ticketing system for coordination. Developed algorithms using LabVIEW and Excel to analyze large data for USAA. This involved Machine Learning techniques for density based spatial clustering and pattern recognition. This improved pattern recognition from 85% to 97%.

Oklahoma City, Ok, Us

I was primarily responsible for writing control software for environmental test chambers using LabVIEW. This included updating legacy code and constructing new drivers to work on Windows 7. I also wrote custom macros for Excel using VBA.

I teach, train, and consult to provide the optimal results for the customer’s needs. This has been centered on a basis of software, design and experience. My primary experience has been focused on CNC machinery. I also work with individuals and small companies. Specialties include LabVIEW CLAD level certification and short turn job specific programming assignments (WinSoft, Santa Ana).

Fort Worth, Texas, Us

My primary responsibilities included writing custom software using LabVIEW, C# (2010), VBA (Excel), and C++. These programs were typically used to control waterjet systems and custom automation equipment implementing motor control, limit switches, temperature readings and pressure sensors. Waterjet programming typically interfaced with Delta Tau’s PMAC line of control cards. I also worked as Program Manager for the delivery of custom waterjets. This included maintaining schedules, budgets and deliverables.Other responsibilities include deriving and implementing forward and reverse kinematic functions defining 5-axis robotic machinery. I also trained and give demonstrations in Mastercam and Surfcam(CNC machining)..

I specialized in writing on-site custom LabVIEW solutions for various needs where the customer didn’t have the need for a full-time employee. These solutions included implementing stepper motors, CCD’s and fluid valve controls to take air samples and perform a non-linear curve fit against a known library of spectral samples (Gryphon Technologies, Dallas); motor controller PCA’s and high voltage motors (4600V) (Toshiba Motors, Houston); and converting existing LabVIEW code to C# for an existing test stand (Rockwell Collins, Rapid City).I also designed PCA’s for medical applications to meet RoHS compliance (Sanmina-SCI, Huntsville). I developed a new architecture to streamline and secure the communication between a Windows-based interface and a microcontroller acquisition system using C# and assembly on a spinal decompression device (FDA Class IIa). I documented medical devices that were no longer supported by the original manufacturer for repair. This included wiring connection diagrams, tooling requirements, BOM’s (to include current crosses), and troubleshooting guide.

My primary responsibility was to design, support and maintain a new electronic sub-system for a spinal decompression medical device. I developed a custom Windows-based application using Microsoft’s .NET Framework written with C# and Visual Basic, and a custom PCA with a PIC Controller to interface to all peripherals. Software features developed include specialized data acquisition drivers, custom graphing and printing tools using GDI+, patient record storage and retrieval, remote control for customer service, automated faxing tools, and record synchronization with a custom Pocket PC. I also developed a Pocket PC application to compliment the existing system using Microsoft’s Compact .NET Framework in C#.

My primary responsibility was to develop control software for End-of-Line testers using LabVIEW for automotive motors. They tested Cogging Torque, Ripple Torque, Torque Constants (Kt), and Hall-Timing accuracy. All test data was stored into databases using ActiveX to link LabVIEW with Access. I developed data retrieval and analysis tools using Excel and Visual Basic for Applications using ADO for process analysis. These were distributed using Office XP’s Developer’s distribution tools. I developed an archival NT service written in Visual Basic.NET for redundant data storage to a dedicated server.

My primary responsibility was to improve process flow for quartz SAW wafer fabrication. This entailed developing a Statistical Process Control package plant-wide using a combination of Excel, Access, and Visual Basic for Applications and LabVIEW. Other responsibilities included investigating and developing new rounding processes. Using water-jet technology, the rounding process was reduced in cost and time, and yield was improved by 75%. This system used a PLC and industrialized controller in conjunction with precision stepper motors and high-pressure water controls (>50kPSI)

Sarasota, Fl, Us

My primary responsibility was hardware design of vibration sensors. This included schematic capture and PCB layout (OrCAD), documentation generation of PCA and system specifications and BOM’s (costed and assembly).Further responsibilities included upgrading existing design files to current release formats and upgrading PCB’s to take advantage of surface-mount technology.

Houston, Texas, Us

My primary responsibility was hardware design of personal computers in the sub-$1000 market. This included schematic capture (OrCAD & PowerVIEW) and documentation generation for PCA specifications, BOM’s (costed and assembly), and layout recommendations. As Lead Engineer, I was responsible for all product deliverables. This included motherboard, chassis, peripherals, labels, cosmetics, agency certifications, and software image. I was directly responsible for all electrical integrity of the motherboard design.Further responsibilities included product testing and project management. First-hand testing responsibilities included prototyping bring-up/debugging and system integration compatibility. I also coordinated several other groups dedicated to more specific testing, such as Wide Area Testing, Hardware Evaluation, ROM Audit, Manufacturing Diagnostics, Software Development, etc. Lastly, I was a beta tester for Windows 98 and other pre-release software titles.

Austin, Tx, Us

My primary job responsibility was designing micro-controller PCA’s for the company’s automated metering systems. I also designed and implemented an engineering database for part numbering and selection and vendor history (MS Access). Technologies used were LonWorks and proprietary telephone communications. Infrared sensors were used for data collection and unit activation. Board designs were combination surface-mount and thru-hole with double-sided components. Switching and linear supplies were integrated into the board designs, which were constrained to 1” x 4”.

SPEC was primarily a defense sub-contracting company. My responsibility was to implement in a two-step phase a specific theory. The first step was using “off the shelf” rack components (such as RF generators and signal measurement devices) and controlling them with a PC or Mac using LabVIEW and GPIB and Data Acquisition cards. Once a theory was proven, I designed dedicated circuits and reduced the system size for deliverability and manufacturability. Technologies used were: industrialized PC’s, single-board controllers (PC104), Optics (IR, visible and UV lasers, RF signal generators (PLL and DDS), filters and modulators; surface-mount and thru-hole PCB’s designed for RF, audio and digital applications; and mechanical design and assembly of enclosures for electronics and optics. Programming was in C, Assembly, and LabVIEW.
