"I will take your smart ring/Watch or fitness tracker idea from concept to working prototype"


I help founders and innovators turn their wearable ideas into functional, tested prototypes fast and reliably.


Specializing in smart rings, smart watch, fitness trackers, and compact health devices, I manage the entire process from initial concept to a complete working prototype.


What you get:

  • Professional PCB design (rigid or rigid-flex)
  • ESP32 firmware with sensor integration
  • Low power optimization & Bluetooth performance
  • Clear documentation and prototype guidance


I excel at turning vague or complex ideas into real hardware that works. Many clients come unsure about technical details I handle everything with clear communication and structured execution.


Ready to build your smart ring, fitness tracker, or wearable device?


Message me with your idea and Ill send you a custom plan


Thank you.


Marcus
