About

I am a Mechanical CAD Designer specializing in 3D CAD modeling, product design, mechanical engineering, and product development. I help startups, manufacturers, engineers, inventors, and businesses transform ideas, sketches, drawings, and existing products into accurate and manufacturing-ready CAD designs.

My services include:

• 3D CAD modeling and mechanical part design
• Product design and development
• Mechanical assemblies and assembly design
• 2D technical and manufacturing drawings
• Design for Manufacturing (DFM) and Design for Assembly (DFA)
• Sheet metal and enclosure design
• Prototype and 3D printing design
• Reverse engineering and CAD conversion
• Product modifications and design optimization
• Manufacturing-ready documentation and CAD files

I focus on practical engineering, accurate dimensions, functional mechanisms, clean modeling, and designs that are suitable for prototyping and manufacturing.

I can work from sketches, images, PDFs, existing CAD files, reference products, or basic concepts and develop them into detailed 3D models and technical documentation.

Software experience includes Fusion 360, SolidWorks, AutoCAD, and other CAD/engineering tools.

Whether you need a single mechanical part, a complete assembly, a product prototype, or development of a concept from scratch, I can help take your design from idea to production-ready CAD.
