Mechanical Design Engineer with over seven years of experience in 3D CAD modelling, mechanical assemblies, engineering drawings, reverse engineering, FEA, and design for manufacturing.

I have worked on automotive components, consumer products, industrial machinery, and aerospace-related projects, developing designs from initial concepts and 3D-scanned geometry through prototyping and production-ready documentation. My experience includes plastic and machined components, GD&T, dimensional tolerancing, injection-moulded part design, and manufacturing considerations.

I am proficient in SolidWorks, Autodesk Inventor, AutoCAD, and Solid Edge. I currently work in Abu Dhabi as a Mechanical Engineering CAD Expert, where I develop technical projects and guide complete engineering design workflows.

I am always interested in opportunities involving mechanical product development, automotive design, aerospace, advanced manufacturing, and engineering innovation.
