À propos de moi
I am an embedded firmware and IoT developer specializing in Nordic Semiconductor solutions, wearable health devices, and connected electronics. I develop firmware for nRF91, nRF52, nRF53, ESP32, and STM32 platforms, supporting LTE-M, NB-IoT, BLE, and wireless communication. My expertise includes ECG, PPG, and IMU sensor integration, MQTT, HTTPS, GNSS, low power optimization, PCB bring-up, and prototype development. I help startups, engineers, and product developers turn hardware concepts into functional, reliable, connected device prototypes through quality firmware development.
