   Engineer

   I am a Senior Embedded Firmware Engineer with over 11 years of professional experience in designing and developing IoT devices, low-power embedded systems, and BLE-based products. I specialize in firmware architecture, sensor integration, and wireless communication protocols, helping clients turn hardware concepts into reliable and production-ready solutions. My technical expertise includes nRF52 Series (Nordic), ESP32, STM32, and TI CC2640R2 microcontrollers. I develop firmware using C/C++, Zephyr RTOS, FreeRTOS, ESP-IDF, and Nordic SDK, focusing on low-power design, modular structure, and code reusability. I’ve implemented various features like BLE GATT services, motion detection, NFC reading, cloud communication (HTTP/MQTT), and OTA updates. I focus on delivering firmware that is scalable, power-efficient, and field-tested. I take ownership from concept and prototyping to testing and deployment, ensuring seamless integration between firmware, hardware, and mobile/cloud interfaces. If you are looking for a dependable embedded engineer who can deliver end-to-end firmware development, BLE connectivity, and IoT integration, I can help you bring your product from idea to production with precision, performance, and reliability.
