About this Gig


Need a smartwatch or smart ring PCB that's compact, reliable, and ready to actually work in real life not just look good on screen? Youre in the right place.


I help startups, engineers, and creators build professional wearable electronics with custom PCB design, BLE connectivity, sensor integration, and embedded firmware development.


From ultra-compact smart rings to advanced smartwatch systems, I focus on creating low-power wearable devices that are optimized for size, battery life, and performance.


What I Can Help You Build:


  • Smartwatch PCBs
  • Smart ring electronics
  • BLE wearable devices
  • Health & fitness tracking systems
  • Custom sensor-based wearables


Features I Can Integrate:


  • Bluetooth Low EnergyBLE
  • Heart rate, ECG, PPG & motion sensors
  • Battery charging & power management
  • Embedded firmware development
  • Low-power optimization for longer battery life


What You'll Receive:


  • Professional schematic & PCB layout
  • Gerber & BOM files
  • Firmware source code support
  • Production-ready design files
  • Clean and compact wearable PCB design


I focus on delivering wearable electronics that are practical, manufacturable, and ready for prototyping or production
