I design real products that get manufactured - not just 3D models. Manufacturing-ready CAD, prototyping, and Design for Manufacturing (DFM)-driven product development for industrial and consumer products. I’m a Product & Industrial Designer with a strong engineering background, specializing in manufacturable product design, mechanical systems, and production-ready CAD. My core focus is not just creating geometry, but developing real products that can be prototyped, tested, manufactured, assembled, and scaled. I have over 10 years of hands-on experience in automotive and industrial product development, particularly within the automotive aftermarket, where design decisions directly impact tooling cost, durability, logistics, and user safety. 📐 What I Do Best I support products from early concept through production validation, with a strong emphasis on: 🔖 Design for Manufacturing (DFM) 🔖 Design for Assembly (DFA) 🔖 Prototyping strategies (FDM, SLA, MJF, CNC) 🔖 Injection molding, sheet metal, and machined parts 🔖 Tolerance management, interfaces, and real-world constraints 📐 End-to-End Product Development Experience I’ve initiated and completed 100+ projects, including: - New product development - Product and process optimization - Cost reduction through redesign - Capacity and efficiency improvements - Innovative R&D projects - Patent-oriented design and prior-art interpretation I’m comfortable evaluating designs from a patentability and IP-risk perspective and aligning concepts accordingly. 📐 Services - Product development from concept or existing reference - Mechanical and industrial 3D CAD (Siemens NX) - Manufacturing drawings (GD&T, BOM, weld symbols) - Design for CNC, sheet metal, injection molding–ready design - Reverse engineering & 3D scan to CAD - Prototyping strategies and iteration planning - Mold-aware part design (plastic & tooling logic) - Technical support during supplier/manufacturer discussions ⏲ Engagement Model I work hourly for: - Iterative product development - Prototyping-heavy projects - Ongoing engineering support I prefer fixed-price for: - Clearly defined parts or assemblies - Manufacturing drawings & production packages - Design reviews and feasibility studies In all cases, scope is defined upfront to avoid surprises on both sides. 📌 Primary CAD Tool: Siemens NX, AutoCAD and Geomagic Design X I work primarily in Siemens NX, which is widely used in high-end automotive and industrial manufacturing. I can deliver clean, fully editable STEP / STL / Parasolid files, and I regularly convert and work with SolidWorks, Fusion 360, Rhino, SketchUp, and scan-based data. If you use SolidWorks or another CAD system, this is not a limitation — deliverables are always production-ready and compatible. ✒️ Supporting: - Adobe Photoshop / Illustrator / InDesign - Excel (costing, BOMs, comparisons) 📌 If you’re looking for someone who can own the technical side of your product, speak the language of manufacturers, and reduce risk before production—this is where I add the most value. 📐 Automotive Aftermarket Products Development Experience I’ve led and executed the design and development of many production-ready products, including: ✒️ Roof Rack Carrier Bars: Designed 12+ variants, 200+ mounting brackets & kits optimized for different roof types, load cases, and regulations. ✒️ Modular & Extendable Roof Basket: A configurable, scalable system designed for modular manufacturing and logistics efficiency. ✒️ Vehicle Roof-Mounted Bicycle Carrier: A dual-orientation design supporting different wheel diameters with integrated safety locking. ✒️ Roof Rails for Commercial Vehicles: A design that allows for the mounting of various equipment on the roof of commercial vehicles while also giving the vehicle a stylish and aesthetic appearance. ✒️ Vehicle Roof-Mounted Canoe Carrier: A compact, user-friendly system optimized for ease of use and space efficiency. ✒️ Running Boards & Side Steps: Adaptable designs with interchangeable visible components for multiple vehicle platforms. ✒️ Vehicle Roof Platform: A modular and scalable design featuring T-slot mounting channels for different components, allowing for the adaptation of tents or other equipment. ✒️ Hitch Bike Rack: Tiltable, foldable, transport-optimized, configurable for mounting 2 or 3 bikes, competitive in the global market and focused on price-performance. These products were developed with tooling, assembly, durability, and cost in mind—not just form.
