MUHAMMAD W.

DFM Mechanical Designer | Fabrication, Sheet Metal & Machine Design

I am a Mechanical Design Engineer with over 20 years of experience Specializing in Design for Manufacturing (DFM), sheet-metal design, fabrication, reverse engineering, and manufacturing drawings. While many CAD models look good on screen, they can be difficult to manufacture in the workshop. I Specialized in turning designs into practical, production-ready parts and assemblies that are easy to cut, bend, weld, and assemble. I transform ideas, sketches, measurements, and existing CAD models into practical, buildable solutions that simplify production, reduce costs, and improve reliability. Key Strengths  Sheet-metal design for laser cutting, bending, and welding  Manufacturing-focused CAD design and model improvements  Production-ready DXF, STEP, and shop drawings  Reverse engineering from photos, sketches, measurements, and existing parts  Assembly simplification and part-count reduction  Tolerance stack analysis and GD&T  2D manufacturing and welding drawings  BOMs and exploded/assembly drawings  Design modifications for cost and weight reduction  Production support and monitoring of my own designs 🏆Software 🚀 SolidWorks — Certified 🚀 Autodesk Inventor 🚀 Onshape 🚀 AutoCAD ✔️Reverse Engineering & Product Development Experience Worked as part of an Engineering Design Team on the reverse engineering of industrial machinery, including truck-mounted concrete pump assemblies and hydraulic cylinders. Responsibilities included: ◉ Measuring and reverse-engineering complete assemblies and components ◉ Creating detailed 3D models and BOMs ◉ Modifying designs for cost reduction and Weight optimization ◉ Supporting FEA when required ◉ Implementing customer-driven design changes ◉ Creating detailed 2D manufacturing drawings with GD&T and welding information ◉ Preparing exploded and assembly drawings for manufacturing ◉ Supporting product design and development ◉ Monitoring production of my own designs My approach is always practical and manufacturing-focused: I design parts based on how they will actually be manufactured, assembled, and used—not simply how they look in CAD.
