Most CAD models look good on screen.
Very few are actually ready for manufacturing, fabrication, or real-world production.
I help startups, manufacturers, fabrication shops, engineering teams, and product developers create production-ready CAD models, sheet metal designs, fabrication drawings, 3D printable parts, and manufacturing documentation that can go directly into production.
If you are struggling with:
✔CAD files that cannot actually be manufactured,
✔Incorrect flat patterns, bend issues during sheet metal fabrication,
✔Poor fabrication drawings with missing dimensions
✔Weak product designs and non-Optimized 3d printable designs,
✔Messy assemblies and unclear BOMs
✔Poor communication and delayed delivery,
✔Freelancers disappearing mid-project,
✔Constant revisions due to manufacturing mistakes,
then I can help.
With more than 6 years of experience, I specialize in turning sketches, concepts, PDFs, STEP files, STL scans, and rough ideas into clean, organized, production-ready engineering deliverables.

Are you looking for the Mechanical designer/Welder/ and 3D printing and Additive manufacturing specialist who understands how things actually get built in the real world?
I don't just create pretty 3D renders. I design high-performance, manufacture-ready products engineered to save you time, eliminate costly redesigns, and streamline production from day one.
With over a decade of hands-on engineering, additive manufacturing, Welding (IWP) and industrial metal fabrication experience, I bridge the gap between digital CAD concepts and the physical shop floor.
🌟 Why Work With Me?
Most designers stop at the screen. I’ve spent the last 10 years machining, welding, and 3D printing the very products I design. When you work with me, you get zero-error Design for Manufacturability (DFM) tailored specifically to your chosen production method—saving you thousands in wasted material, rework, and prototyping delay.
🎯 Core Capabilities & Expertise
-CAD & Mechanical Design: 2D Drafting, Parametric 3D Modeling, Assemblies, Tolerancing, DFM/DFA (Design for Assembly).
-3D Printing & Rapid Prototyping: Additive manufacturing optimization, functional prototype iteration, snap-fit mechanics, and print-in-place design (PLA, PETG, ABS, TPU).
-Metal Fabrication & International Welding: Fully versed in ISO welding positions, WPS, welding symbols, and structural drawings across ARC, MIG/MAG, TIG, Oxy-Acetylene, and Resistance welding.
-Machining & Production: Hands-on operational mastery in Lathe, Milling, NC Lathe, Slotting, Shearing, Rolling, Hydraulic Universal Drills, and Precision Grinding.
Prototyping & Field Guidance: Comprehensive technical documentation, shop-floor assembly guides, and step-by-step production oversight.
💡 What I Bring to Your Project
1. Production-Ready CAD: Clean, structured parametric files optimized for CNC, sheet metal, injection molding, or 3D printing.
2. Cost & Time Savings: Direct application of DFM principles so your product can be economically produced without manufacturing bottlenecks.
3. End-to-End Prototyping: Seamlessly taking your idea from rough sketch to 3D print/prototype to shop floor mass production.
Whether you need a functional 3D prototype, complex structural fabrication drawings, or an engineer to lead a product from concept to manufacturing, I’m here to make it happen flawlessly.
