Moustafa M.
Embedded system engineer & Flutter mobile app developer
As an experienced Embedded and IoT developer, I specialize in building reliable, high-performance systems using STM32, Arduino, ESP32, and ATmega32 microcontrollers. With deep expertise in MQTT and robust device-to-device communication, I deliver smart, connected solutions that bridge the gap between hardware and software. I also have hands-on experience building LoRa-based systems, including projects using the RAK3172 module, enabling long-range, low-power communication for scalable IoT deployments. In addition to my IoT capabilities, I’m a skilled Flutter mobile app developer. I design and develop responsive, user-friendly apps with a focus on clean architecture, maintainability, and performance. I’m proficient in state management, Firebase, Supabase, local storage, and API integration — ensuring every app is scalable, efficient, and production-ready. I’m passionate about delivering high-quality, end-to-end solutions that align with your business objectives. Let’s work together to bring your ideas to life!
