Prototype & Mechanical Product Designer | SolidWorks CAD | 3D Modeling & Product Development
About
Need a Mechanical Product Designer who can take your product from concept → 3D CAD → detailed assembly → prototype → manufacturing-ready documentation?
I specialize in Mechanical Product Design, Prototype Development, SolidWorks CAD, 3D Modeling, Assembly Design, Mechanism Design, DFM, and Engineering Drawings, helping startups, inventors, manufacturers, and engineering teams transform concepts, sketches, existing components, and prototypes into precise, functional, and buildable products.
With experience in mechanical product development, 3D part modeling, assemblies, mechanisms, enclosures, product redesign, prototype development, reverse engineering, and technical documentation, I focus on designs that are engineered for real-world use—not simply models that look good on screen.

WHY BUYERS HIRE ME
I don’t stop at creating a visually impressive 3D model. I focus on how the product will actually work, fit together, be assembled, prototyped, and manufactured.
My approach is detail-focused, practical, and engineering-driven, with attention to dimensions, tolerances, component interfaces, mechanisms, material considerations, manufacturability, assembly requirements, and prototype constraints.
I understand that buyers need more than a CAD file they need a design that can communicate the product clearly, support prototyping, reduce design problems, and move the project closer to manufacturing.
Whether you have a rough sketch, hand drawing, physical prototype, existing CAD file, reference images, measurements, or simply a product idea, I can turn your requirements into a structured and professional CAD solution.
READY TO DEVELOP YOUR PRODUCT?
If you're ready to move your product from idea to professional prototype-ready design, let's get started.
Send me your requirements, sketches, dimensions, existing CAD files, or reference images. I’ll review the project requirements and help turn your concept into a precise, functional, and buildable product.
