Top 1% ranked Computer graphics 3D CAD/CAM expert here on freelancer. I can research and design any idea and have many tools to get that idea to reality. I´ve been working on Research & Development for 17 years now. I use Blender, ZBrush, Inventor, Fusion360 and any other software to model and visualize products and ideas. My clients have included Hewlett Packard, Procter & Gamble and NASA. Nevertheless, you don´t have to be an expert on design to work with me, if you speak English or Spanish, value your project and want to learn and create, I´m your guy. If you have experience, we probably will get along very well too. I have been working through the years on diverse industries, from faucets to medical prototypes to real spaceship technology. Fulfilling 100% satisfaction on every project is an important part of every deal. If your project needs quality and you are prepared to invest in quality, I am your best choice.
