About this Gig

Hello and welcome!


I develop reliable embedded firmware and microcontroller solutions for IoT devices, prototypes, and custom electronics products.


I can program and integrate microcontrollers such as ESP32, STM32, Arduino, RP2040, and nRF52 for connected devices and embedded applications.


My services include:

  • Embedded C/C++ firmware development
  • Microcontroller programming
  • ESP32, STM32, Arduino & nRF52 development
  • Wi-Fi, Bluetooth & BLE connectivity
  • IoT device firmware
  • Sensor and actuator integration
  • UART, SPI, I2C, CAN & GPIO
  • MQTT and cloud communication
  • Power management and battery applications
  • Firmware debugging and optimization
  • Hardware-firmware integration
  • Prototype and production-ready firmware


Whether you have a circuit that needs firmware, an existing codebase that needs improvement, or an IoT product idea that needs to become functional, I can develop a structured solution around your hardware.


Please make sure to Send me your requirements, schematic, datasheet, or existing code and let's build your embedded system.
