About

I am a Mechanical Engineer specializing in 3D CAD modeling, mechanical design, and manufacturing drawings, with professional experience in CAD design and manufacturing environments. I have hands-on knowledge of mechanical components, sheet metal fabrication, production engineering, and the design-to-manufacturing process.

I am proficient in SOLIDWORKS, AutoCAD, Fusion 360, and DraftSight, with expertise in 3D part modeling, assembly design, 2D technical drawings, sheet metal design, and manufacturing documentation. I also have experience preparing Bills of Materials (BOM), applying dimensions and tolerances, and developing designs with Design for Manufacturing (DFM) principles in mind.

I hold SOLIDWORKS professional certifications, including CSWP and CSWPA, reflecting my commitment to technical excellence and continuous professional development.

I focus on delivering accurate, practical, and manufacturing-ready designs while maintaining clear communication and attention to engineering details. I am open to freelance opportunities in mechanical CAD design, 3D modeling, technical drawing, and product development.
