Positions and Work Experience

2004 -2018 Senior Software Developer, Designed and developed a product for Correlating FEM and Experimentally derived modal models, including Least Squares Geometry Alignment, Degree-of-Freedom (DOF) mapping, Modal Assurance Criteria (MAC) comparisons, Orthogonality Comparisons and Mode Pairing based on correlation criteria. Capability also included the ability expand Test mode shapes to the full FEM space. Part of a team that specified the design and developed an Experimental Modal Analysis product that displayed clean stability diagrams for multiple MDOF parameter estimation algorithms. The result gives the user scaled Modal Models for further structural dynamic studies. Part of a team that specified the design and developed an Operating Deflection Shape Acquisition and Analysis product. Part of a team that developed a COM based geometry component, that allowed geometry display and mode shape animation to be embedded in the PULSE Labshop application as well as allowing for live Active-X documents in Word, Excel and PowerPoint., Brüel & Kjær, North America, Cincinnati, OH

2002 -2004 Applications Engineer III, Analyze, design and Develop enhancements to Levi Strauss & Co.’s MANDATE® Warehouse Management Software (WMS) and SageX Warehouse Control Software. Provided Tier 3 and Tier 4 software support to three Customer Service Centers (CSC’s) across the US. Troubleshooting, software maintenance and quality assurance. Software development languages included C, awk and sed scripting in UNIX and SQL database queries. Interact with the Customer Support Centers’ management team and core workers to provide training for new functionality and improve current systems and processes., Levi Strauss & Co., Hebron, KY
