I am a passionate product designer and engineer that specializes in creating durable and functional 3D prints via CAD. My expertise stems from a strong background in and love for drafting, machining, engineering, and aviation. I pride myself on my obsessive attention to detail and ability to lose myself in projects. Rest assured, I am a devote follower of the “measure twice, cut once” philosophy. I prefer to personally prototype and test each and every design before giving it my stamp of approval to ensure that every single aspect of my work; from the manufacturing to the consume experience is both carefully tailored my client’s vision and reflects my high standard of quality. If you have a great idea for a product I would love to bring it to life for you!

Hi, my name is Zack and I’m a mechanical engineer. I have approximately 5 years of work experience involving work with CAD design, 3D printing, design for manufacturing, and project management. I have used Freeform, Solidworks, Inventor and Fusion 360 design software. I primarily use Autodesk Inventor and Fusion 360 today. I graduated from Northern Arizona University in Fall 2020 Cum Laude with a degree in mechanical engineering. I’m currently working as a senior manufacturing engineer/project manager where I take customer requirements, convert them into 3D models for approval and take them through the manufacturing processes. I am responsible for all projects through each step of our processes in a sheet metal environment so I am familiar with laser cutting, CNC machining, bending, welding, assembly, and powder coating. I also tutored mathematics in college where I learned crucial problem solving skills.
