About this Gig

Looking for a professional PCB engineer who can design high-speed, RF, and power electronics boards with proper signal integrity, EMI control, and reliable routing? Youre in the right place.

I specialize in advanced multilayer PCB design for modern electronics, including high-frequency RF circuits, high-speed interfaces (USB-C, HDMI, LVDS, MIPI, PCIe, DDR), and high-power SMPS/Buck/Boost/PoE systems.

All designs follow solid engineering practices: impedance control, clean return paths, differential pair tuning, low-noise layout, thermal optimization, and manufacturable stackups.


What I can design:

  • High-speed digital boards (USB-C, DDR, PCIe, HDMI)
  • RF boards (2.4 GHz, 5.8 GHz, GNSS/GPS, LoRa, BLE, WiFi)
  • Power electronics (Buck/Boost, SMPS, PoE, high-current)
  • Mixed-signal and multilayer PCBs (412 layers)
  • IoT devices, sensor hubs, MCU/SoC boards
  • Hardware architecture + schematic design


What you will receive:

  • Complete schematic
  • Professionally routed PCB
  • Controlled-impedance routing
  • BOM with part sourcing
  • Gerber/Drill files ready for fabrication
  • 3D model of the PCB
  • EMC/EMI-aware layout practices
