About
I help hardware teams develop high-speed PCBs and identify schematic and layout issues before fabrication.
I am a Senior Hardware Design Engineer with more than seven years of PCB design and review experience, including over 100 board reviews. My background includes complex military and commercial hardware systems, high-density multilayer boards up to 20 layers, GPU chip-down layouts, and 0.5 mm-pitch BGA layouts.
I can support your project with:
• Schematic design and review: Circuit development, component selection, interface connections, and identification of potential design issues.
• PCB layout and review: High-speed routing, component placement, BGA layout, and multilayer board design.
• Experience with Altium, KiCad, Matlab, Allegro Cadence,ProgeCAD, EasyEDA, LTspice, PSpice,Arduino IDE, Espressif.
• High-speed and digital interfaces: PCIe Gen 5, USB, digital video interfaces, UART, I2C, and SPI.
• Embedded and IoT hardware: ESP32, PIC microcontrollers, Raspberry Pi platforms, and systems using BLE and Wi-Fi.
• Manufacturing deliverables: Gerber files, bills of materials, and PCB assembly documentation.
My additional experience includes PLC systems, cable harnesses, AC/DC circuit analysis, motors, lasers, and photonics.
Whether you need an independent review of an existing design, updates to a board, or support developing new hardware, I can help define the next steps and deliverables.
Message me with a brief description of your project, the CAD software you use, and the support you need.
