Orhan Tolga B.

I am a Mechanical Engineer specializing in automotive engineering, mechanical design, vehicle integration, mechanisms, and production-ready CAD development.

I have extensive hands-on experience in commercial vehicle engineering, buses, minibuses, special-purpose vehicles, passenger door systems, mechanical mechanisms, sheet-metal components, brackets, assemblies, and custom engineering solutions.

I primarily use Autodesk Inventor for 3D parametric modeling, mechanical assemblies, sheet-metal design, mechanism development, and production-ready engineering drawings. I also use Autodesk AutoCAD for 2D technical drawings, layouts, manufacturing documentation, and engineering modifications.

My experience covers the complete engineering process, from initial feasibility and concept development to CAD design, engineering calculations, manufacturing drawings, prototype development, assembly, vehicle integration, testing, and production support.

My core capabilities include:

• Mechanical and automotive product design
• Autodesk Inventor 3D parametric modeling
• Complex mechanical assembly design
• Mechanism and linkage design
• Vehicle packaging and component integration
• Sheet-metal component design
• Autodesk AutoCAD 2D technical drawings
• Production-ready manufacturing drawings
• Design for Manufacturing and Assembly (DFM / DFMA)
• Tolerance definition and dimensional control
• BOM and technical documentation
• Vehicle weight distribution and axle-load calculations
• Prototype development and design validation
• Reverse engineering and product improvement
• Supplier and manufacturing coordination
• Engineering problem solving for production

I have worked extensively on commercial vehicles, minibuses, buses, low-entry vehicle applications, special-purpose vehicles, and electric passenger door systems.

My approach goes beyond creating CAD geometry. I focus on developing practical engineering solutions that can actually be manufactured, assembled, tested, maintained, and used reliably in real-world applications.

I am available for remote freelance projects, mechanical design assignments, automotive engineering support, product development, CAD modeling, manufacturing documentation, and long-term engineering collaborations.
