About

I have a strong background in precision mechanics, tolerance stack analysis, FEM analysis, manufacturing & cost and prototyping. Always looking to expand my knowlegde, and find solutions for new challenges.

Experience

  • Cognex Corporation (Full-time · 8 yrs 2 mos)
    • Principal Mechanical Engineer
      Feb 2022 - Present · 4 yrs 6 mos

      As a Principal Mechanical Engineer in Cognex, I oversee the entire lifecycle of product development, from initial concept to final release. Tasks include designing components that are die-cast, machined, and injection-molded, ensuring they meet stringent quality and performance standards. Additional responsibilities include: Thermal Analysis: I evaluate and optimize the thermal performance of designs to ensure they can withstand operational temperatures. Tolerance Analysis: I ensure that parts fit together correctly by analyzing and specifying acceptable limits of variation in physical dimensions. Finite Element Analysis (FEA): I use advanced simulation techniques to predict how products will react to real-world forces, vibration, heat, and other physical effects. Creating Cogs Overviews: I develop comprehensive overviews of the components and their costs, ensure that we hit the cost of goods target in our products. In addition to these tasks, I have full responsibility for the product’s mechanical functionality, ensuring it meets all performance and quality standards. I also lead projects when necessary, coordinating efforts across teams to achieve project goals. Furthermore, I mentor one or more team members, providing guidance and support to help them grow professionally.
