INDUSTRIAL CAD & PRODUCT DESIGN SPECIALIST I help startups, manufacturers and R&D teams turn ideas, legacy designs and complex mechanical challenges into practical, manufacturable products. With 8+ years of experience and Top-Rated Plus status on Upwork, supported by successfully completed projects and consistent five-star feedback, I provide reliable CAD and mechanical product-development support to clients worldwide. Whether you are creating a new product, improving an existing design, resolving a manufacturing problem or modernising your engineering workflow, I can work as an extension of your team from initial requirements through production. WHAT I CAN HELP YOU WITH • Concept development and mechanical product design • 3D CAD modelling of parts, assemblies and mechanisms • Detailed manufacturing and fabrication drawings • GD&T, tolerance stack-up and dimensional analysis • Design for Manufacturing (DFM) to improve manufacturability, reduce production complexity and control cost • Design for Assembly (DFA) to simplify assembly, reduce part count and minimise installation errors • Design Failure Mode and Effects Analysis (DFMEA) to identify design risks, potential failure modes and preventive actions • Sheet-metal, machined-part and weldment design • Plastic parts, moulding considerations and 3D printing • Reverse engineering from parts, scan data or reference drawings • Structural and thermal analysis using Ansys • Root-cause analysis, troubleshooting and design optimisation • Prototype development, design review and validation COMPLETE PRODUCT LIFECYCLE SUPPORT I support startups without an in-house engineering team as well as established companies requiring additional design capacity. My involvement can include converting an idea into an engineering concept, developing parts and assemblies, preparing production drawings and BOMs, supporting prototype manufacturing, reviewing test feedback and implementing improvements. I can also assist with supplier identification, vendor development, RFQ documentation, technical clarifications, manufacturing coordination, quality requirements, pre-dispatch checks and product validation. This helps reduce design uncertainty, prevent avoidable manufacturing iterations and move products from concept to production with a structured process and quick turnaround. CAD AUTOMATION & ENGINEERING PROCESS IMPROVEMENT I help companies reduce repetitive CAD work using Autodesk Inventor iLogic. This includes parameter-driven parts and assemblies, configurable product families, design rules, forms, automated drawings and BOM generation. These solutions are particularly useful for engineer-to-order and configurable products where dimensions, components or options change frequently. Structured CAD automation can improve consistency, reduce manual errors and shorten engineering lead times. LEGACY DATA CONVERSION & CAD MIGRATION I help companies modernise hand drawings, PDFs, old 2D files and legacy CAD data by converting them into accurate, editable and production-ready models. Services include: • Hand sketches and paper drawings to 2D or 3D CAD • PDF, DWG and DXF drawings to parametric 3D models • Legacy 2D drawings to modern parts and assemblies • CAD reconstruction with proper design intent and feature history • Migration between SolidWorks, Creo, Inventor and other CAD platforms • Updated drawings, BOMs and manufacturing documentation • Model restructuring for future modification, reuse and automation INDUSTRIES SERVED My experience includes robotics, automotive, agriculture, offshore equipment, defence-related products, marine systems, heavy engineering, architectural products, industrial equipment and consumer products. SOFTWARE & ENGINEERING TOOLS • CAD: SolidWorks, Creo Parametric, Autodesk Inventor and AutoCAD • Simulation: Ansys Workbench and Multiphysics • Reverse engineering: Geomagic Design X • PLM/PDM: Windchill, Autodesk Vault, Soliworks Vault HOW I WORK I begin by understanding the product, operating conditions, constraints and required deliverables. I identify missing information, technical risks and suitable development stages before proceeding. Throughout the project, I maintain clear communication, structured reviews, realistic timelines and documented decisions. I can coordinate directly with your engineering team, manufacturers and suppliers to keep the project moving efficiently. LET’S DISCUSS YOUR PRODUCT OR ENGINEERING CHALLENGE Whether you are a startup developing your first physical product, an OEM facing a design or production issue, or a company looking to automate or migrate its CAD workflow, share your idea, existing files or current challenge. I will help define the right engineering approach and move your project toward a manufacturable, validated and production-ready solution.
