I’m a Mechanical & Product CAD Designer with 10+ years of freelance experience in 3D CAD modeling, mechanical design, product development, and technical drafting, with a strong focus on SolidWorks. I help clients transform concepts, sketches, images, existing components, and 2D drawings into accurate, practical, and manufacturing-ready CAD designs. My experience covers both industrial machinery and technology products, including projects that progressed beyond CAD development into prototyping, testing, and functional working products. Core CAD & Product Design Expertise • SolidWorks 3D part and assembly modeling • Mechanical and product design • Industrial machinery and equipment design • Plastic and electronic enclosure design • Sensor and electronics housing design • Sheet metal components and assemblies • 2D manufacturing drawings and detailing • 2D-to-3D CAD conversion • Reverse engineering from existing parts, images, or measurements • CAD modifications and design improvements • CAD models for prototyping, 3D printing, and manufacturing • Exploded views, assembly documentation, and product visualization with photo realisti rendering. Relevant Project Experience Industrial Machinery — Zreyas Technology I worked as a freelance CAD/mechanical designer on industrial machinery and product-development projects. One of my key projects was the design and development of a Cold-Pressed Oil Extraction Machine, where I was involved from CAD design through prototype development, functional testing, and design improvements. The machine was successfully prototyped and developed as a fully functional working system, providing practical experience beyond 3D modeling alone. Sensor & Electronic Enclosures — MachineSense As a freelance CAD designer, I worked on sensor, electronic, and technology-product enclosures, developing detailed SolidWorks models with consideration for component fit, assembly, accessibility, manufacturing, and practical product requirements. These enclosure designs were developed for functional products and prototype/production development. Medical & Technology Products — Opteev / MachineSense As a freelance Mechanical & CAD Designer, I supported Opteev and MachineSense during the COVID-19 period on significant medical and technology-product development projects. My work included SolidWorks enclosure and housing design for ViraWarn and FeverWarn medical-device products, including component fit, assembly, mechanical design, revisions, prototyping, and manufacturing considerations. These were fully functional products developed for real-world deployment during the pandemic, giving me hands-on experience designing practical enclosures around actual electronic, sensor, and mechanical components. My approach is to understand the functional and manufacturing requirements of a product before developing the CAD design. I focus on dimensions, component fit, assembly, manufacturability, usability, and practical production considerations—not just creating a visually accurate 3D model. What You Can Expect ✓ Accurate and well-structured SolidWorks models ✓ Practical mechanical and product design solutions ✓ Manufacturing-oriented CAD development ✓ Clear 2D technical and manufacturing drawings ✓ Professional communication and regular progress updates ✓ Careful attention to dimensions, fit, assembly, and functionality ✓ CAD support from concept through prototype development Whether you need a mechanical component, complete assembly, industrial machine, product enclosure, 2D manufacturing drawing, reverse-engineered part, or concept developed into a functional prototype, I can help turn your requirements into a practical CAD solution.
