Experience

• CAD/CAE Engineer SumiRiko Technical Center America, Inc. · Full-time Oct 2016 – Present 8 yrs 1 mos Novi, MI, United States -SumiRiko Technical Center America, Inc. (SRK-TCA) is a center for the design and testing of rubber parts for the larger Sumitomo Riko, an automotive supplier. SRK-TCA makes parts for many automotive clients, mainly Ford and Nissan.
  
  -I do most of my work at SRK-TCA conducting Finite-Element Analysis (FEA) on rubber and metal parts, for which I use the CAE software listed in the Skills section. I operate these programs to conduct many variations of CAE analysis (Static, Dynamic, Resonance/Normal Modes, Dynamic Compliance, etc.) on designs that have a variety of material properties (linear vs. non-linear, isotropic vs. anisotropic, etc).
  Several of these designs have gone on to be implemented in Ford vehicle designs.
  
  -Over time, I have specialized in the creation of tetra-meshes (for linear material) and hex-meshes (for non-linear material) for use in FEA, chiefly employing Altair Hyperworks to do so. I have gained roughly 1500 hours of experience with meshing over the last 3+ years.
  
  -In addition to CAE, I am a main CAD designer for SRK-TCA's testing department, for which I operate CATIA. Most of my CAD work involves the design of fixtures for testing, mapping the lab layout for redesign, or improving safety in the lab by designing new additions, such as ramps.
  
  -I learned how to simulate the injection-molding process of resin parts with Moldex3D, and earned the official certification for this software. To convert the fiber orientation of these resin parts into anisotropic material properties, I utilize Altair Converse and MSC Digimat.
  
• Engineering Intern Contour Metrological and Manufacturing, Inc. · Internship May 2016 – Aug 2016 3 mos Troy, MI, United States -Contour is a company which develops high-precision optics with precision down to the micron level.
  
  -While at Contour, I developed skills on how to create CAD designs with SolidWorks, and learned the importance of high-accuracy, quality, and attention to detail with regards to creating 3D models and 2D drawings, as well as the principles of GD&T. Part specifications were kept within a precision tolerance of plus-or-minus 5 microns, so design optimization and accuracy were paramount.
