Marnick J.

Mechanical Engineer (Prototype Design, Build, and Testing)

If you have a product idea you want to bring to life, I can help you turn it into something you can eventually hold in your hands. I’m a hands-on Mechanical Engineer with over 9 years of experience developing products from the first sketch all the way to fully functional prototypes. I work across every stage of the design process, including concept development, CAD modeling, manufacturing, testing, and assembly. Over the years, I’ve gained practical experience with a wide range of fabrication methods such as laser cutting, creating precise DXF files, CNC machining, milling, lathe work, and general mechanical assembly. This means you’re not just getting a designer, but someone who understands how a product is actually built and how it needs to function in the real world. Whether you need a clear product concept, detailed 3D models, functional prototypes, or a design refined for production, I can support your project from beginning to end. I can help you move smoothly through the entire development process, from the initial idea to a prototype you can test and hold. From the first conversation to the final result, you will always know where your project stands. If you’re ready to turn your idea from an initial thought into a physical product, I’d be happy to help you take that next step.
