About
Need a CAD designer who can take your idea, sketch, existing part, drawing, or product requirement and turn it into an accurate, functional, and manufacturing-ready design?
You are in the right place.
Whether you are an inventor with an idea that exists only on paper, a startup developing a physical product, a manufacturer needing production drawings, an engineering company looking for reliable CAD support, or a business that needs an existing component recreated or improved, I understand that you are looking for more than someone who can simply create a 3D model.
You need someone who understands what you are trying to build, pays attention to the technical details, communicates clearly, and delivers CAD work that can actually support the next stage of your project.
That is the approach I bring to every project.
I specialize in CAD Design, 3D CAD Modeling, Mechanical CAD Design, Product Design, Product Development, Mechanical Drafting, Technical Drawing, Manufacturing Drawings, Reverse Engineering, Design for Manufacturing (DFM), Prototyping, and production-ready CAD documentation.
My focus is on creating accurate and practical designs based on your specific requirements. I take the time to understand the purpose of the component or product, how it will be used, the intended manufacturing process, the required dimensions, materials, assembly requirements, tolerances, and the final files you need.
My CAD services include:
• 3D CAD Modeling and 3D Product Modeling
• Mechanical CAD Design
• Mechanical Parts and Components
• Product Design and Product Development
• 2D CAD Drafting
• Technical and Engineering Drawings
• Manufacturing and Production Drawings
• Assembly Design and Exploded Views
• Reverse Engineering and Part Recreation
• Sketch, Image, PDF, and 2D Drawing to CAD Conversion
• Existing CAD Design Modification and Redesign
• Design for Manufacturing (DFM)
• CNC Machining-Ready CAD Designs
• Fabrication and Laser-Cutting Designs
• Sheet Metal Design
• Prototype Design and Development
• 3D Printing-Ready CAD Models
• CAD File Conversion and Translation
• Assembly Documentation and Bill of Materials
• Manufacturing Documentation and Design Support
If you already have a rough sketch, hand drawing, photograph, reference image, PDF, measurements, 2D drawing, physical component, or existing CAD file, I can work from your available information and develop it into a more structured and detailed CAD solution.
For inventors and product developers, I understand how important it is to preserve the original idea while making the design more realistic and practical for development. Your concept may still be changing, and you may need help refining dimensions, components, assemblies, or the overall structure before moving toward a prototype. I can work with you through that process rather than treating your project as simply another modeling task.
For startups and product businesses, I understand that CAD is often an important part of turning an idea into something that can be prototyped, tested, manufactured, presented to manufacturers, or developed further. The goal is not just a visually appealing model. The design needs to make sense for its intended purpose and production requirements.
For manufacturers, fabricators, and CNC businesses, accuracy and clarity are critical. I can help prepare detailed CAD models, technical drawings, manufacturing drawings, component designs, assemblies, and other documentation needed to move a project toward production.
For engineering teams and companies that already have established workflows, I can provide additional CAD support for individual projects, design modifications, drafting requirements, mechanical components, assemblies, product development, and ongoing design work.
I also understand that sometimes the starting point is an existing physical component rather than a new idea. If you need to recreate a part from measurements, photographs, drawings, or an existing component, reverse engineering and part recreation can help turn that information into a usable CAD model for modification, prototyping, replacement, or further development.
My approach is always client-first.
Before beginning the actual design work, I want to understand what you need, why you need it, how the design will be used, and what the final deliverable should accomplish. I believe asking the right questions at the beginning can prevent unnecessary revisions later.
During the project, I focus on clear communication, careful attention to dimensions and requirements, organized CAD files, and making sure the work continues to match your expectations. If something about the design requirement is unclear, I would rather clarify it than make assumptions that could affect the final result.
I also pay attention to the practical side of CAD design. Depending on the project, your model may eventually need to be CNC machined, 3D printed, laser cut, fabricated, assembled, molded, or manufactured
