That’s Me

(Next to my hero, Adam Savage)


Hi, I’m Yosei, and for as long as I can remember, I have loved THINGS. What I mean by that is, I’ve always had a fascination with the objects that are a part of our daily lives. My childhood was defined by Optimus Prime, LEGO, model planes, and earth-movers. My resulting love for linkages, pulleys, and pistons led me down a path to begin making mechanical creations of my own, to earn a degree in mechanical engineering, and to develop my unfaltering passion to create wonderful things from ideas.

I believe the objects we interact with each day can have a profoundly positive effect on the quality of our lives. However, I feel a responsibility to consider not just the immediate quality of our own lives, but also those of other species with whom we share this planet, as well as future generations. I believe that good, considered design serves as an important nucleus to begin shaping a better world, and securing a bright future. Let’s get Making!

Here’s What I’m Good At

This is my wheelhouse! I can fabricate things in wood, metal, plastics, and even fabric. It’s hard to list everything, but here are a few ways I make things:

  • 3D printing

  • Metal machining

  • Carbon fiber composite lay-ups

  • Small-batch resin casting

  • MIG welding

I excel at making things look like they could sit on a store shelf. A couple of things I can do for your business are:

  • Photo + presentation-ready prototypes

  • User Testing


I’ve spent over a decade (and counting!) working as an engineer and am familiar large portions of the product-development pipeline. Some of my skills and knowledge include:

  • Mechanical design of:

    • Molded composites

    • Injection molded plastics

    • Machined metals

    • Mechanical assemblies

  • Technical engineering drawings

  • DFM + DFA

  • Manufacturer communication

    • Requests for quotes

    • Tooling design requirements

    • Component sourcing


I like to say that while I’m trained as an engineer, I’m a designer at heart. I’m self-taught as a designer and seek inspiration from the best. I can provide:

  • Concept Artwork

  • 3D Renders

  • Marketing/Pitch Assets

  • Mechanical Animations
