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 🤝🚀
