About

I specialize in mechanical design and product development, helping startups, inventors, and manufacturers transform concepts into production-ready products. I create accurate 3D CAD models, assemblies, engineering drawings, and manufacturing documentation using SolidWorks and Fusion 360.

My expertise includes mechanical part design, product development, sheet metal design, plastic part design, reverse engineering, enclosure design, design for manufacturing (DFM), design for assembly (DFA), and prototype-ready CAD models. Every design is developed with attention to functionality, manufacturability, and production efficiency.

I deliver complete engineering documentation, including technical drawings, assemblies, BOMs, exploded views, STEP files, STL files, and production-ready files for CNC machining, sheet metal fabrication, injection molding, and 3D printing.

Either you're developing a new product, improving an existing design, or preparing files for manufacturing, I focus on delivering practical engineering solutions that support reliable production and long-term product success.
