Designing Machine Vision based Automation, Metrology and Inspection for Industry.Originally began as zero dollar part time startup to provide machine vision based systems for industrial automation in the Portland Metro Area.Now a full time occupation as we try to grow into more complex solutions.Responsible for all aspects of software architecture, team leader, hiring team members, mentoring, requirements gathering/management. Excellent domain knowledge in automated workflow based vision systems for both 2D and 3D (point cloud) metrology and inspection. Experienced in "big picture" design. Skills C#, C++, Managed C++, Cognex, Matrox, 3D imaging processing, SQL, Peer Group factory automation, SCRUM, openmp, parallel processing. Microsoft Visual Studio, Microsoft Team Foundation Server.Machine vision projects related to automate machine vision on AeroTech A3200 CNC controller and Nikon Metallagraph optical microscope platformDeveloped Android phone apps for data logging, data visualization, GPS and map presentation and data upload to Windows OS. Extensive experience with Android Studio, Android SDK, java

Semiconductor Wafer Inspection and Metrology on Nanometrics Unifire 7900 platform based off of Zygo Unifire 7900 platform which Nanometrics acquired. Worked closely with optical scientists, customers and marketing stakeholders to develop software using agile process and scalable architecture. Communicated key design paradigms through extensive vision documents.Continued to developed hierarchical tree workflow environment with shape based image regions that allows end customers to efficiently create their own measurement recipes.Extensive use of Design Patterns/C# inheritance to create activity based recipe framework and pluggable objects/user controls. Developed stitched image based inspection workflows to capture large areas of the wafer/shot/die with multiple camera acquisitions. Extensive end user configurable image processing via clipping, filling, surface removal and filtering.Broad collaboration with internal and customer stakeholders to develop and evangelize design concepts and theories of operation. Customers include Intel, TSMC, Samsung, and Western Digital. C#, C++, Managed C++,.NET 5.0, TFS, Resharper, OpenMP, Syncfusion Diagram, ILNumerics, Cognex VisioPro, VS2013, 64 bit Win 7. DebugDiag.

Drone Avionics and Imaging Sensor related projects based upon Win7 Embedded and WinCE. Realized potential of unifying Insitu’s two aircraft models, Integrator and ScanEagle to create unified avionics code base and truly common ground station controller (ScanEagle2). Performed Gap Analysis on system control concept for data management within the integrating flight control and the video tracking system. Created initial project vision documents for stakeholders. Meet cost and development time cycle constraints using off shelf components. Concurrently design flight system and video tracking system. Concurrently design software and hardware and hardware component selection. Extensive reuse of existing software with modified hardware abstraction layer and redesigned tracking system that reused in house and 3rd party tracking algorithms. Architectural design of throughput performance within size, weight, power and temperature constraints of the existing airframe. Extensive use of software only system simulation and Hardware-in-Loop Simulation prior to ground test and test flights. Experience with large legacy VC++ and C# code base. Selected Intel Atom processor module and selected ARM processor and coded ARM based Bulk USB IO component and Win32 device driver. Specified UART, NIC, mSATA, miniPCIe and other hw level components. Created custom Windows 7 Embedded Standard images. Noted that Windows based avionics would never receive FAA approval, proposed port VxWorks. Replaced multi circuit board DSP based camera/video system with single off shelf Core i7 solution keeping 90% software compatibility. Filed US Patents for non-IATR drone specification. Extensive experience with Matrox based machine vision and Mentor Graphics VNA CAN bus hardware and software on ARM. COM-Express modules and Carrier Card concepts.Windows Embedded Standard, IAR Workbench, ARM processor, VxWorks, Device Driver, USB Device Development, C#, C++, Perforce, SCRUM, Hardware Design, CANBus

Managed and technically lead a ten person development team to create FEI’s IC3D product. IC3D is a metrology application that automates several of FEI’s Wafer Dual Beam Microscopes (Scanning Electron Microscope + Focused Ion Beam) and lamella based Transmission Electron Microscopes.IC3D is the Data Storage industry standard for in-line, in-FAB, cross sectional metrology based process control. Over one hundred microscopes have been installed costing between $1.5M - $3.5M. IC3D is also used as the basic for automated TEM Sample Preparation.Invented Automated Machine Control and Metrology concept that provides a graphical workflow editor/debugger. The User creates automated workflows by linking and grouping graphical shapes, in a Visio like environment using scaled image as a backdrop, to produce automated sequences to cross-section and measure complex sub surface features, such as Semiconductor Shallow Trench Isolation (STI) structures and Data Storage read/write head structures. Graphical shapes are associated with behavioral regions for image acquisition, feature alignment, Focused Ion Beam cross-sectioning (drilling), machine vision pattern recognition and edge detection and dimensioning (metrology).
