Mattia A.

I help startups and product companies turn ideas into functional, manufacturable products—and existing CAD into clear, photorealistic product visuals. I'm a Mechanical & Product Design Engineer with 8+ years of experience in full-cycle product development, from concept and mechanical architecture to production-ready CAD, engineering validation, prototypes, and manufacturing support. 100% Job Success on Upwork | 5.0 client rating across 33 reviews PRODUCT DEVELOPMENT & MECHANICAL DESIGN • Concept development, mechanical architecture, and detailed product design • SolidWorks 3D modeling, complex assemblies, and CAD cleanup • Design for Manufacturing and Assembly (DFM / DFA) • Injection-molded plastic parts, sheet metal, machined components, and 3D-printed prototypes • Mechanisms, mechanical transmissions, and planetary gearboxes • Production-ready 2D drawings, bills of materials (BOMs), and technical documentation • Prototyping, supplier coordination, and manufacturing support PRODUCT RENDERING & CAD-TO-RENDER I also help communicate how a product looks and works through photorealistic visualization. • CAD preparation and cleanup for rendering • CAD-to-render workflows using KeyShot and SolidWorks Visualize • Materials, lighting, and photorealistic product rendering • Product visuals for design reviews, presentations, and marketing You can engage me for complete mechanical development or a focused task: updating an existing CAD model, preparing drawings and BOMs, cleaning up an assembly, or creating product renders. ENGINEERING ANALYSIS & VALIDATION My CAE background supports design decisions throughout development: • Finite Element Analysis (FEA) and structural analysis • Static and dynamic simulations • Topology and design optimization • Multi-body dynamics • Engineering calculations, component sizing, and gear-system analysis I combine engineering performance with practical manufacturing and assembly requirements, working with manufacturers and suppliers to resolve issues during prototyping and production. RELEVANT EXPERIENCE My work includes portable energy products, injection-molded enclosures, sheet-metal structures, internal component packaging, copper connections and busbars, mechanical transmissions, planetary gearboxes, and EV-related components. I've supported projects from early concepts and prototypes through development for serial production, collaborating with clients, electronics engineers, manufacturers, and suppliers.
