Mechanical CAD designer with over 10 years in industry. I have worked on industrial condensers and evaporators for freon, ammonia and glycol systems (HVAC-R) — 3D modeling, 2D fabrication detailing and technical datasheet verification. I also have shop-floor background in electrical and electronic product lines: UPS units, control panels, outlets, switches and power strips — injection-molded plastic parts, sheet metal, forming, stamping and electronics. That is why I model with manufacturing in mind: how the part is actually cut, bent, molded, machined, welded and assembled. Types of parts I work with: - Bent sheet metal (carbon steel, stainless steel, aluminum), with flat patterns and DXF for laser and punching - Machined parts, with tolerances and surface finish - Injection-molded plastic parts - Extruded aluminum and plastic profiles - Weldments and steel structures - Parts for 3D printing - Automotive appearance parts - Molds and dies What I deliver: 3D models, fabrication-ready 2D drawings, bills of materials, and reverse engineering from samples or measurements. My models are built parametrically, so a dimensional change updates the assembly and the drawings instead of forcing a remodel — revisions are fast and cheap. I deliver in STEP, STL, DWG/DXF and PDF, so you can open and edit the files on whatever platform you use. English B2 (goFLUENT certified). Based in Brazil, available across US and European time zones.
