If your product design looks perfect in CAD but you're not sure it will actually survive the factory floor, that uncertainty is going to cost you. I'm a Product Design Engineer and Mechanical Design Engineer with 8+ years of experience in industrial design and manufacturing-ready CAD, and my job is to make sure your product gets built right the first time, not redesigned after a costly manufacturing mistake. From concept to product, I handle the full product development cycle so nothing gets lost between your idea and what actually ships. Recent work, and what it actually does: A. Sump Tube Alert System. Designed an automated water level control mechanism for swimming pools that detects rising water and shuts it off before overflow, with zero manual monitoring needed. Full industrial enclosure design integrated around the embedded electronics, delivered as a complete prototype ready product. B. Animal Feeding Chute, 500+ part SolidWorks assembly. Engineered a large scale mechanical assembly that feeds 6 animals at once instead of one at a time, cutting manual labor significantly. Full structural steel framing, gates, hinges, latches, and gate operation mechanisms modeled and managed as one complex parametric assembly. C. Topology optimized mouthguard. Applied topology optimization to reduce weight in a high impact mouthguard design, without compromising the structural strength it needs to protect against impact, keeping it light enough and comfortable enough for real use. What I deliver: Product, Mechanical & Industrial Design Concept to production ready CAD in SolidWorks, covering machine design, enclosure design, and snap fit design for plastic components. DFM/DFA for Manufacturing Design for injection molding, CNC, sheet metal, and 3D printing, so parts work correctly the first time they hit the factory floor. Engineering Drawings & GD&T Manufacturing drawings with complete tolerance stack ups and supplier ready documentation. FEA & Structural Simulation Validating designs before they're built, catching failure points before they cost you money. Reverse Engineering Converting existing parts or physical products into accurate, editable CAD. Prototyping & Rendering 3D printed prototypes and photorealistic renderings for testing, investor decks, or marketing. Tech Stack: SolidWorks, CAD Design, DFM/DFA, GD&T, FEA, CNC Machining, Injection Molding, Sheet Metal Design, 3D Printing, Reverse Engineering Message me before you commit to manufacturing. A short conversation now can save you months of rework and thousands in tooling costs later.
