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.
