About
Mechanical design engineer with 18+ years of experience taking products from concept to manufacturing. I started on the shop floor as a CNC machining technician, so every design I deliver is built to be manufactured, not just modeled.
What I can do for you:
3D modeling and assemblies in Siemens NX, CATIA V5, SolidWorks and Creo
Production-ready 2D drawings with GD&T and tolerance stack-up analysis
Welded steel structures, frames and sheet metal design
Design for Manufacturing (DFM): cost reduction and simplification of existing parts
Cast and machined parts: gearbox housings, bearing housings, transmission blocks
Gear and bearing life calculations to DIN/ISO standards
Conversion of sketches, legacy drawings or scanned parts into clean CAD models
Background: defense land vehicles, expedition vehicles, textile machinery, pneumatic tools and machine commissioning. As design approval authority in my current role, my drawings go directly to manufacturing.
I deliver native files plus STEP and PDF drawings, communicate clearly in English and Turkish, and meet deadlines.
