I’m Tuan D., an engineer who bridges mechanical design with electrical, controls, and software integration to turn ideas into reliable, manufacturable products. My experience spans concept development through detailed drawings and prototype validation, so clients get complete, production-ready solutions without juggling multiple freelancers. Rather than overwhelm you with tool lists, I focus on clear communication, rapid iteration, and data-driven decisions that keep budgets and timelines on track. If you need practical engineering that moves smoothly from first sketch to shop floor, let’s connect and map out the next steps.
