About

I am a Mechanical Design Engineer with more than 12 years of experience in mechanical product development, CAD design, assembly design, and engineering projects.

My primary CAD system is Siemens NX, complemented by practical experience with Creo Parametric, Autodesk Inventor, and CATIA V5.

Throughout my career, I have worked on projects in automotive, mechanical engineering, power tools, industrial cleaning equipment, agricultural machinery, and plant engineering. My focus is on developing functional, manufacturable mechanical components and assemblies – from concept development and design optimization to production-ready 3D models, technical drawings, and BOMs.

Selected project experience includes:
• Modular electric motor platforms for power tools
• Automotive exhaust systems from concept to series production
• Modular tank systems for industrial cleaning equipment
• Mechanical assemblies for Power-to-X reactor systems
• Interior components for agricultural machinery
• Fixtures, welding tools, assembly tooling, gauges, and cubings

Core competencies:
• Siemens NX
• Mechanical Design & Product Development
• Assembly Design
• Concept & Variant Development
• Design Optimization
• Creo Parametric
• Autodesk Inventor
• Design for Manufacturing (DFM)
• GD&T / ISO GPS
• Technical Drawings & BOMs
• PLM/PDM: Teamcenter, SAP/ECTR, Smaragd, PRO.FILE

I work independently, integrate quickly into existing engineering teams, and am experienced in remote collaboration within customer systems via VPN.

I am available for freelance mechanical design and CAD projects, particularly projects involving Siemens NX, mechanical assemblies, product development, and design optimization.
