My background is 20 years of mechanical design in film and television special effects, which means bespoke fabricated equipment, tight deadlines, and drawings that have to work on the shop floor because there is no second chance on a film set. That experience includes a 1,000-tonne underwater rotating structure cited as the largest special effects rig ever built for a feature film. The work I do is mechanical design across the full range: concept development, detailed 3D modelling, structural and hydraulic analysis, fabrication drawings, and site commissioning. I work directly with fabricators and machinists, and I understand what it takes to turn a drawing into something that actually gets built and works first time. My primary tools are Onshape (Certified Professional) and SolidWorks, with AutoCAD for 2D work. For analysis I use Mathcad and SkyCiv. Hydraulic and pneumatic system design is a core part of my practice. My background covers fabricated steel structures and weldments, sheet metal, modular mechanical systems, motion rigs, dynamic and rotating machinery, hydraulic and pneumatic actuation, and design for manufacture across a wide range of production methods. I carry design authority on everything I deliver. I size and check my own work, document my calculations, and produce technical packages that fabricators and clients can actually use.

Need a mechanical product that can move from concept to manufacturing without costly redesign? I help startups, product developers, and manufacturers turn ideas, sketches, existing products, and technical requirements into accurate SolidWorks models and production-ready documentation. I am a Certified SolidWorks Professional (CSWP) and Senior Mechanical Design Engineer with over 13 years of experience in product development and manufacturing design. I am an Upwork Top Rated Plus freelancer with a 99% Job Success Score, more than $100K earned, over 5,900 hours worked, and 380 successfully completed projects. I am also recognized as a Cad Crowd Top Designer and Gold Award winner. My experience includes SolidWorks parts and assemblies, mechanical mechanisms, sheet-metal enclosures, fabricated structures, CNC-machined components, plastic parts, injection-molding DFM, 3D-printable models, reverse engineering, ISO GD&T, FEA, BOMs, exploded views, and detailed manufacturing drawings. I can support your project with: Concept development and mechanical design SolidWorks 3D modeling and assemblies Product redesign and design improvement Sheet-metal parts, cabinets, covers, and flat patterns CNC components and manufacturing drawings Plastic enclosures and injection-molding design 3D-printable STEP and STL files Reverse engineering from samples, images, or measurements FEA and basic mechanical validation GD&T, BOMs, DXF files, and production documentation My work covers consumer products, electronic enclosures, machinery, manufacturing fixtures, welded structures, aerospace equipment, display models, prototypes, and custom mechanical assemblies. I focus on practical engineering, manufacturability, dimensional accuracy, organized CAD files, clear communication, confidentiality, and dependable delivery. My goal is to provide designs that look professional, function correctly, and can be manufactured efficiently. Whether you need a new product developed, an existing design reconstructed, a prototype prepared for 3D printing, or a complete manufacturing package, I can support the project from initial concept through final production release.

Need fabrication-ready CAD models, drawings, and cutting files that can move directly into production? I help fabrication shops, product teams, and small manufacturers turn sketches, PDFs, photos, STEP/STL files, and existing CAD into accurate parts and assemblies, shop drawings, flat patterns, BOMs, and laser-ready DXF/DWG files. I work primarily in SolidWorks and AutoCAD, matching the output to the production workflow—native CAD files, STEP/STL, DXF/DWG, or PDF drawing packages as required. My focus is not only making the model look correct. I check the details that cause shop-floor problems: units and scale, wall thickness, bend allowance, clearances, hole sizes, mating parts, revision consistency, and manufacturing assumptions. What I deliver: • SolidWorks parts, assemblies, and production drawings • Sheet metal models, flat patterns, bend information, and DXF/DWG files • Weldment frames, fabrication drawings, cut lists, and BOMs • STEP/STL repair, CAD cleanup, and file conversion • 3D-print-ready parts and assemblies, including STL/3MF exports, fit and clearance tuning, and print-bed-aware part splitting • Enclosures, brackets, housings, frames, and multi-part assemblies • PDF drawing packages and KeyShot renders when required I am a Mechatronics Engineer with 5+ years of hands-on mechanical design and fabrication experience. My work has included steel scaffolding and formwork systems, storage systems, sheet metal and weldment assemblies, production drawings, BOMs, cut lists, and shop-ready files. Client feedback consistently highlights my fast turnaround, clear communication, attention to detail, and careful handling of revisions. I keep projects organized and raise technical questions early so the final files remain accurate and ready for review or production. Send me your sketch, PDF, STEP/STL, or existing CAD file. I will review the scope, identify missing technical details, and recommend the cleanest production-ready path.
