I will develop zephyr rtos firmware for nordic nrf52 nrf53 nrf54 mcus

Are you looking for an experienced embedded firmware developer for a Nordic nRF52, nRF53, or nRF54 project using Zephyr RTOS?

I develop reliable, power-efficient, and production-ready firmware for Nordic Semiconductor MCUs and connected embedded devices.

With 15+ years of experience in electronics and embedded systems, I can help with new firmware development, existing firmware modification, debugging, driver development, BLE applications, RTOS architecture, and low-power optimization.

What I Can Develop

• Zephyr RTOS firmware development
• Nordic nRF52 / nRF53 / nRF54 firmware
• BLE / Bluetooth Low Energy applications
• Custom BLE GATT services and characteristics
• BLE advertising, scanning, connections and notifications
• Sensor and peripheral drivers
• GPIO, ADC, PWM, UART, SPI and I2C
• Interrupts, timers and work queues
• Thread synchronization and inter-task communication
• DeviceTree configuration
• Kconfig configuration
• Nordic nRF Connect SDK development
• Power management and low-power firmware
• Battery-operated device optimization
• Bootloader and DFU / firmware update support
• Logging, diagnostics and debugging
• Firmware architecture and code organization
• Existing firmware debugging & optimization
