Mo S.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I engineer complete electromechanical products—not just CAD or PCB files. From SolidWorks mechanical design and Altium PCB development to embedded control and functional prototypes, I connect the mechanical, electronic, and control systems into one working product. I’m a Top Rated Plus Mechatronics / Hardware Engineer on Upwork (Top 3% Worldwide), with experience developing machines, robotics, electronic controllers, sensor systems, and hardware prototypes. **Core engineering:** • Mechanical & Product Design — SolidWorks, assemblies, mechanisms, sheet metal, machine design, drawings, DFM/DFA • Electronics & PCB — Altium Designer, schematics, PCB layout, power electronics, sensors, drivers, custom controllers • Embedded Systems — Arduino, AVR, STM32, C/C++, communication interfaces, hardware/firmware integration • Mechatronics — motors, actuators, encoders, motion control, robotics, sensor-based machines I focus on the details that determine whether a product actually works: component selection, mechanical clearances, thermal behavior, current requirements, manufacturability, wiring, control logic, and real-world testing. My work includes robotic machines, industrial equipment, motorized mechanisms, custom PCBs/controllers, sensor systems, and functional prototypes. If you already have CAD, schematics, PCB files, sketches, or a prototype, I can work from your existing design rather than rebuilding what is already done. If you're developing a physical product or machine, send me the current design or requirements and we can identify the most critical engineering issues first.
