CAD & Engineering Software

SolidWorks | AutoCAD | Autodesk Inventor | Siemens NX / UG NX | CATIA | Mastercam | ANSYS | Fusion 360

Experienced with 2D & 3D CAD modeling, FEA, engineering documentation, GD&T, FMEA / PFMEA, and manufacturing processes.

⚙️ Manufacturing & CNC Experience

My background includes hands-on experience in CNC machining and programming, including G-code and M-code, tooling, cutting tools, inspection, blueprint reading, tolerances, and manufacturing processes.

This practical manufacturing knowledge helps me create designs that are not only accurate, but also realistic and practical to manufacture and assemble.

From Sketch to Finished Design

A hand sketch, photo, PDF, image, blueprint, or existing CAD file is all I need to get started.

I can transform your concept into a professional 3D CAD model and 2D engineering drawing according to your requirements.

Whether you need:

✔ A simple part modeled
✔ An existing CAD design modified
✔ A manufacturing drawing created
✔ A complete assembly designed
✔ A product concept developed
✔ A design reviewed for manufacturability

—I can help.
