About this service

Bring your complex engineering projects to life with senior-level precision. Backed by over 20 years of robust industry experience inside elite corporate ecosystems - including BAE Systems, Volvo, and Scania - I deliver production-ready 3D CAD models and mechanical designs engineered for flawless real-world execution.

What I offer:
• Parametric 3D part modeling and complex mechanical assemblies
• Design for Manufacturing (DFM) tailored to castings, injection molding, and sheet metal
• Strict application of GD&T (Geometric Dimensioning & Tolerancing) standards
• Clean, uncorrupted feature tree structures for seamless future edits

Leveraging a deep operational history in CATIA V5/V6 alongside current proficiency in SolidWorks, I bridge the gap between enterprise capability and flexible contract support. I am fully equipped to handle advanced surfacing, geometric logic, and structural spatial constraints. Let’s build something robust.
