Hoang D.

Hardware & IoT Product Engineer | Production-Ready PCB, MCU & Embedded Systems I help startups and product teams turn ideas into reliable, manufacturable hardware products — from early concept and prototyping to mass production (1K–10K+ units). With 6+ years of hands-on experience in hardware & embedded system design, I specialize in production-ready PCB design, MCU-based systems, and hardware debugging, ensuring your product is stable, cost-effective, and ready for manufacturing — not just a working prototype. I have worked on complex designs involving high-speed interfaces, mixed-signal circuits, power management, and embedded control systems, helping teams reduce design iterations, avoid costly respins, and accelerate time-to-market. What I Can Help You With ✔ End-to-end IoT & hardware product development ✔ Schematic design & multi-layer PCB layout (production-ready) ✔ Hardware debugging & root-cause analysis ✔ MCU, FPGA & high-speed interface integration ✔ BOM optimization, Gerber generation & DFM support ✔ Support from prototype → EVT/DVT → mass production Technical Expertise Hardware & PCB Design -Schematic capture, PCB layout, stack-up & impedance planning -Power integrity, signal integrity & mixed-signal design -Tools: Altium Designer, KiCAD, OrCAD, EasyEDA Embedded Systems -8-bit / 16-bit / 32-bit ARM microcontrollers -FPGA-based designs and external memory interfaces (SDRAM, DDR2/3/4/5, LPDDR) Analog & Digital Circuits -ADC, DAC, Op-Amps, voltage regulators -Transistors, MOSFETs, power & protection circuits Communication Interfaces -RS-232, RS-485, SPI, I²C, I²S, UART -USB, Ethernet PHY, LVDS, CAN, LIN, PCIe Production & Validation -Hardware bring-up & validation -Lab equipment: oscilloscope, DMM, soldering & rework -Manufacturing support for low to high-volume production Mechanical Integration -Basic 3D CAD support for enclosure & PCB fit validation Why Clients Work With Me ✅ Strong focus on manufacturable & scalable designs ✅ Clear communication with engineering & non-technical teams ✅ Experience bridging R&D and mass production ✅ Practical, real-world hardware — not theory-only designs 📩 If you’re looking for a reliable hardware engineer who can deliver production-ready designs and support your product through manufacturing, feel free to reach out.
