Mehmet Batuhan SAM
Vehicle Geometry & Architecture Engineer | Perceived Quality
Bursa
Summary
I am a Vehicle Geometry and Architecture Engineer working at the intersection of dimensional engineering, vehicle integration, and perceived quality. My core expertise is in dimensional management, including tolerance strategies, isostatism locating systems, chain of dimensions, and measurement methodologies. I have applied this across multiple vehicle projects, working closely with suppliers and cross-functional teams to deliver robust and manufacturable solutions. With hands-on experience across development and industrialization phases, I focus on solving real vehicle issues related to fit, assembly, and perceived quality. My strength lies in bridging geometry, architecture, and perceived quality to identify risks early and drive practical, production-ready solutions.
