About this Gig

I develop ultra low power BLE wearable embedded systems optimized for battery efficiency, stable wireless communication, and compact PCB integration for IoT and wearable applications.


This gig is ideal for startups, wearable prototypes, sensor-based devices, and low-power embedded product development.


Services may include:

  1. BLE firmware development
  2. Wearable PCB design
  3. Nordic nRF52 / STM32 / ESP32 systems
  4. Sensor integration
  5. Battery optimization
  6. Low-power embedded firmware
  7. IoT wearable development
  8. Firmware debugging and testing


My workflow focuses on reliable embedded architecture, efficient power management, stable BLE communication, and manufacturable hardware design for wearable systems.


All projects are developed with attention to performance, reliability, and low average current consumption for optimized battery life.
