Rizwan A.

I am a Senior Mechanical Design Engineer with 15+ years of experience in mechanical design, machine design, Special Purpose Machines (SPM), industrial equipment, skid packages, process piping and manufacturing documentation.

I help companies convert concepts, sketches, PDFs, existing drawings and engineering requirements into accurate 3D CAD models and manufacturing-ready engineering drawings.

What I can do

• Mechanical 3D CAD modelling
• Machine and SPM design
• Jigs, fixtures and automation equipment
• Industrial equipment and skid design
• SolidWorks part and assembly modelling
• Autodesk Inventor modelling and assemblies
• AutoCAD 2D drafting and detailing
• Manufacturing and fabrication drawings
• Assembly and part drawings
• BOM and parts-list preparation
• Sheet metal and structural design
• Reverse engineering from drawings, photographs or existing components
• Design modifications and drawing updates
• Piping layouts and isometric drawings
• P&ID interpretation and piping documentation
• AutoCAD Plant 3D modelling and documentation

### Engineering background

I have worked on SPMs, custom jigs and fixtures, automated equipment, water-treatment skids, oil-filtration systems, process equipment, piping systems, structural frames and industrial machinery.

My experience covers concept development, 3D modelling, design calculations, machine-element selection, detailed engineering, manufacturing drawings, BOM preparation, design review, design optimization and coordination with manufacturing and fabrication teams.

I have also led and mentored engineering teams and worked with international clients and multidisciplinary engineering teams.

Software

SolidWorks | Autodesk Inventor | AutoCAD | AutoCAD Plant 3D | Navisworks | Revit MEP

I focus on practical and manufacturable engineering solutions, not just 3D modelling.

I am available for remote freelance, contract, project-based and ongoing engineering work.

Send me your sketch, PDF, existing CAD file, photograph or project requirement, and I can review the scope and suggest the best engineering approach.
