Great products don't fail because of bad ideas, they fail when engineering problems are discovered too late.
As a Mechanical CAD Engineer, I transform concepts into precise, manufacturing-ready designs that reduce costly revisions, improve functionality, and simplify production. Whether you're developing a new product or refining an existing one, I deliver accurate 3D models, assemblies, technical drawings, and production documentation with a focus on real world performance, precision, and manufacturability not just impressive looking CAD.

FAQ
How do you ensure my product won't fail during prototyping?
Every project is engineered with manufacturability in mind. Where applicable, I use FEA, CFD, DFM, and DFA to detect structural, thermal, airflow, and assembly issues early, reducing costly redesigns.
Why should I contact you before placing an order?
Every engineering project has unique technical requirements. A quick discussion helps define the scope, identify potential challenges, recommend the right solution, and ensure you receive an accurate quote and the best possible outcome.
Will the files be ready for manufacturing?
Yes. You'll receive production-ready deliverables including native SolidWorks files, STEP, STL, DXF, PDF drawings, BOM, and detailed engineering documentation suitable for fabrication.

What if my idea is incomplete or only a rough sketch?
No problem. I can transform sketches, photos, PDFs, or concepts into manufacturable mechanical solutions while identifying potential engineering risks before development begins.
