Hire the Best Circuit Designers
in the United States

In the industry for many years, I am an expert in Electronics Design, Manufacturing and PCB Layout. Credentials include an AS in Electronics, one patent and an IPC CID+ (Advanced Certified Interface Designer). My experience helps bring a high level of competence to your project or design review. I am available for work in any time zone.

# Altium Designer # Work on complex designs with FPGAs (>1000 pins), CPUs, DDR2/3/4, Ethernet Switches. # Most designs have USB, SATA, RGMII, SGMII, 1G/10G Eth, PCIe. # Controlled impedance/length matching, via back-drilling, blind/buried vias, HDI. # Designs range from small (<100 comps) to large systems (multiple PCB >2500 comps each). # Worked on Automotive, Mil-spec, Space, High Power (> 50A, > 500V), Audio, Mixed A/D, & RF. Services provided: # PCB Layout -- High Speed, Mixed A/D, RF, Audio, High Power, Telecom, Test, Mil-spec. # Schematic Capture -- Hierarchical or Flat, BOM selection, Sim/Signal Integrity. # Library Management -- Schematic symbol, PCB footprint, integrated 3D info in footprints. # Electronic Design -- High Speed, A/D, Audio, Mixed. # Electronic Design starting from the ground up to the end.

I'm an Embedded Engineer with 10+ years of experience designing production-ready embedded hardware, RF systems, and multilayer PCBs for industrial, IoT, robotics, automotive, and consumer electronics products. I help startups and companies transform ideas into reliable prototypes and manufacturable products. My expertise covers the complete hardware development cycle, including system architecture, schematic capture, PCB layout, embedded firmware, prototype bring-up, testing, and manufacturing support. My expertise includes: • Embedded hardware design (ESP32, STM32, Nordic nRF, RP2040, NXP, Microchip) • RF PCB design (WiFi, BLE, LoRa, Zigbee, UWB, LTE/5G, GNSS) • Multilayer PCB layout (2 to 12+ layers) • High-speed interfaces (USB, Ethernet, PCIe, CAN/CAN-FD, MIPI, DDR) • Mixed-signal, analog, digital, and power electronics • Battery-powered and low-power embedded systems • EMC/EMI-aware PCB layout and signal integrity • Prototype bring-up, debugging, validation, and DFM review Design Tools • Altium Designer • KiCad • EasyEDA Pro • OrCAD / Allegro • Eagle CAD Firmware Development • C / C++ • ESP-IDF • STM32CubeIDE • FreeRTOS • Bootloader development • Peripheral drivers (SPI, I2C, UART, USB, CAN, Ethernet) I've developed custom hardware for wireless IoT devices, industrial automation, robotics, sensor platforms, wearable electronics, medical devices, battery-powered products, and edge AI systems. My designs prioritize reliability, manufacturability, and long-term product support. Whether you need a complete embedded system, RF PCB, hardware review, or manufacturing-ready design, I can support your project from concept through production with clear communication and practical engineering solutions.

Hi, I’m am an American U.S. based medical device engineer with 15+ years of experience designing, testing, and validating PCB-level electronics for medical, industrial, military, and R&D applications. I specialize in EagleCAD/Fusion360 (primary) and Altium-compatible designs, and have hands-on experience with micro-soldering and bench-level troubleshooting and repair (facilities can be arranged for the right project). If you need help turning a schematic into a manufacturable board, debugging an existing design, or setting up automated testing for your hardware, I can support you from system concept through prototype, verification, and market release. Transparent communication and regulatory-grade documentation come standard—you’ll always know what’s been done, what’s next, and why it matters. Let’s get your design validated and ready to build.
