I’m Sharay, a Product Designer with over 7+ years of experience specializing in 3D modeling, 3D printing, STL conversion, and consumer product development. I help startups, inventors, and companies bring their ideas to life, from rough sketches or concepts to production-ready 3D models and technical drawings. My work focuses on creating designs that are not only functional and manufacturable but also optimized for 3D printing, prototyping, and mass production. Whether you're building a mechanical device, a product enclosure, or a printable assembly, I ensure it’s modeled with precision, clarity, and manufacturing intent. Over the years, I’ve designed a wide range of products, including electronics housings, mechanical enclosures, custom tools, wearables, and 3D printable replicas. I also provide services for reverse engineering and mesh-to-CAD conversion, particularly when clients only have STL files or 3D scans and need accurate CAD models from them. Services I Offer: 3D CAD modeling using SolidWorks, CATIA, and Geomagic Design X STL repair, editing, and conversion to solid CAD models Product design for 3D printing, CNC, or injection molding Reverse engineering from scans or reference models Assembly modeling, exploded views, and 2D technical drawings File delivery in STL, STEP, IGES, SLDPRT, DWG, DXF, PDF, and more I understand that many clients come with just an idea, a rough sketch, or a need to upgrade an existing design. I work closely to develop concepts that are production-ready and aligned with your end-use goals. I can also help with design iterations, mechanical fitment, and preparing technical documentation for prototyping or manufacturing. Clients appreciate my clear communication, fast turnaround, and ability to translate vision into professional engineering output. Whether you need just a clean STL file or an entire product designed from scratch, I’m ready to help. Let’s talk about your next project. I usually reply within a few hours.

𝐈 𝐡𝐞𝐥𝐩 𝐟𝐨𝐮𝐧𝐝𝐞𝐫𝐬 𝐚𝐧𝐝 𝐜𝐨𝐦𝐩𝐚𝐧𝐢𝐞𝐬 𝐭𝐮𝐫𝐧 𝐢𝐝𝐞𝐚𝐬 𝐢𝐧𝐭𝐨 𝐫𝐞𝐚𝐥, 𝐦𝐚𝐧𝐮𝐟𝐚𝐜𝐭𝐮𝐫𝐚𝐛𝐥𝐞 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐬 🚀⚙️ If you have a product idea 💡, a broken prototype 🔧, or a design that “looks good in CAD” but won’t survive the real world — that’s where I come in. I lead Efficio Engineering, a product-development studio that designs, simulates, prototypes, and validates real hardware 🧪. My work covers the full pipeline: idea → CAD → simulation → prototype → manufacturing-ready design This means you don’t get a freelancer who only delivers drawings — you get an engineer who makes sure your product actually works when it’s built ✅ 𝐑𝐄𝐀𝐋-𝐖𝐎𝐑𝐋𝐃 𝐈𝐌𝐏𝐀𝐂𝐓 💰 I help clients avoid: • $10k–$50k wasted on failed molds and tooling • Prototypes that break, leak, overheat, or vibrate • Products that work in CAD but fail in the real world My simulation-driven design process catches these problems before you spend money on manufacturing. 𝐖𝐇𝐀𝐓 𝐈 𝐃𝐄𝐋𝐈𝐕𝐄𝐑 🛠️ I specialize in physical product development, including: • Mechanical design for real-world use (enclosures, mechanisms, structures, moving assemblies) • Simulation-driven engineering (FEA, CFD, thermal, vibration) 📊 • Rapid prototyping (3D printing, CNC, laser cutting) 🧩 • Design for Manufacturing (DFM) & Design for Assembly (DFA) • Electro-mechanical integration (motors, sensors, PCBs, batteries, enclosures) 🔌 • Engineering documentation: drawings, BOMs, tolerances, assembly plans 📐 This lets you go from idea → working prototype → production-ready design without switching vendors. 𝐖𝐇𝐘 𝐂𝐋𝐈𝐄𝐍𝐓𝐒 𝐂𝐇𝐎𝐎𝐒𝐄 𝐌𝐄 🧠 Most engineers on Upwork do one piece of the puzzle: CAD, or analysis, or electronics. I built Efficio so clients don’t have to manage five freelancers 👥. You get: • A single technical owner • A multidisciplinary engineering team • Designs that are validated, buildable, and production-ready 🏗️ This is why clients come to me for: • Smart consumer devices 📱 • Wearables & fitness products 💪 • IoT and sensor-based hardware 🌐 • Enclosures, mechanisms & structural parts • High-reliability and safety-critical designs 🔒 𝐓𝐎𝐎𝐋𝐒 & 𝐄𝐍𝐆𝐈𝐍𝐄𝐄𝐑𝐈𝐍𝐆 𝐒𝐓𝐀𝐂𝐊 ⚙️ Mechanical & CAD SolidWorks, Inventor, CATIA Simulation & validation ANSYS (Structural, CFD, Thermal, Modal), SolidWorks Simulation, Star-CCM+ Prototyping & manufacturing FDM & resin 3D printing 🖨️, CNC machining, laser cutting, injection-mold-ready design Electronics integration ESP32, STM32, sensors, motors, power electronics, PCBs, BLE / Wi-Fi 📡 𝐇𝐎𝐖 𝐏𝐑𝐎𝐉𝐄𝐂𝐓𝐒 𝐔𝐒𝐔𝐀𝐋𝐋𝐘 𝐖𝐎𝐑𝐊 📋 We define your product goals and constraints I design and simulate the system We prototype and test 🔬 I iterate until it’s manufacturing-ready You get production files, drawings, and supplier support No guessing. No fragile prototypes. No “it only works in CAD”. If you’re serious about building a real, physical product, let’s talk 🤝🚀
