About

I am a Senior Mechanical Design Engineer with 18+ years of experience turning concepts, sketches, specifications, and engineering requirements into accurate, manufacturable 3D models and production-ready technical drawings.

My background combines mechanical design, industrial equipment, fabrication, piping systems, structural components, and engineering support. I have extensive experience with SolidWorks, Autodesk Inventor, AutoCAD, and AutoCAD Plant 3D, working from initial concepts and layouts through detailed design, manufacturing documentation, and production support.

My core services include:

3D mechanical modeling and assemblies
2D manufacturing and fabrication drawings
Mechanical equipment and component design
Sheet metal and welded structures
Industrial piping and piping supports
Tanks, chutes, platforms, supports, and industrial structures
Bill of Materials (BOM) creation and management
Tolerances, fits, threads, surface finishes, and GD&T
Design for Manufacturing (DFM)
DXF preparation for laser cutting
CAD revisions, redesigns, and drawing conversion
Finite Element Analysis (FEA) using SolidWorks Simulation

I also have experience developing SolidWorks workflow automations to increase engineering productivity and reduce human error, including automatic generation of DXF files from complete assemblies for laser cutting, automated PDF generation, and automated extraction/counting of BOM quantities.

Throughout my career, I have worked on demanding industrial projects in mining, bulk material handling, water and wastewater treatment, piping, and heavy fabrication. At Martin Engineering, I developed equipment and transfer chute solutions for conveyor systems and performed FEA studies on impact beds and chutes subjected to demanding mining loads. At B&F Dias, I worked on industrial water treatment systems, stainless steel, PVC and HDPE piping, structural supports, and large-scale installations.

One of my major projects involved leading the mechanical design of a large water treatment system in Joinville, Brazil, with four 58-meter-diameter tanks. I also participated as lead designer in the implementation of Nereda wastewater treatment technology in Brazil.

I have practical experience working directly with manufacturing, machining, welding, assembly teams, suppliers, and engineering departments. This allows me to design not only for appearance or CAD accuracy, but for real-world manufacturing, assembly, maintenance, cost, and reliability.

Software & Technical Skills:
SolidWorks | Autodesk Inventor | AutoCAD | AutoCAD Plant 3D | SolidWorks Simulation/FEA | GD&T | BOM | DXF | Mechanical Design | Piping | Sheet Metal | Weldments | Manufacturing Drawings | DFM

I hold a Bachelor's Degree in Production Engineering, a Technical Degree in Mechanics, and a degree in Systems Analysis and Development. This combination of mechanical engineering and technology also gives me a strong foundation for CAD automation and process improvement.

If you need an experienced mechanical designer who understands both engineering and manufacturing, I am available for CAD modeling, mechanical design, industrial equipment, fabrication drawings, piping, FEA, design optimization, and CAD automation projects.
