They say experience builds mastery; I say obsession builds excellence. My name is Amin, and for over 21 years, I’ve lived and breathed mechanical engineering, pushing designs far beyond industry standards and delivering results that companies didn’t even know were possible. I started my journey on the shop floor, designing, analyzing, and perfecting real machines. Over the years, I’ve led projects across aerospace, automotive, industrial automation, oil & gas, medical devices, 3D printing, and injection molding industries, collaborating with top-tier companies like Siemens, Rolls-Royce, Bosch, and Medtronic as a consultant and design partner. My mindset was never about “just completing projects.” It was always about dominating benchmarks, raising performance bars, and making sure that when my designs hit production, they perform better, last longer, and look sharper than the competition. Today, I lead a global network of elite engineers, suppliers, and manufacturers. A powerhouse that turns complex ideas into precise, manufacturable, and high-performance realities. Whether it’s a full-scale industrial system, a CFD/FEA analysis, or a next-gen medical prototype, my team and I deliver the kind of quality that sets new standards. When I discovered Upwork, I realized it was the perfect platform to bring that level of engineering to clients worldwide. And the result? Within just a few months — not years — I reached Top Rated Plus, a recognition earned by less than 3% of freelancers here. 🥇🩷 What I bring to the table: 21+ years of multi-industry mechanical design & simulation expertise Mastery of SolidWorks, CATIA, ANSYS, COMSOL, AutoCAD, Siemens NX, Fusion 360, and more Deep understanding of DFM/DFA, prototype development, aerodynamic & structural analysis, and high-precision manufacturing. Proven record of designing for medical, automotive, aerospace, and industrial systems. A strong international network of engineers, suppliers, and manufacturers. If you’re looking for someone who doesn’t just “design parts” , but engineers success, simplifies complexity, and turns your vision into something real and remarkable, you’re in the right place. I'm here to build for you something exceptional together. Because average design is everywhere. But true engineering mastery is rare. In engineering — like in business — you don’t get what you wish for… you get what you build.🎖️
