Firmware Engineer, IoT Developer
Hi, I’m Lutfi — an embedded systems engineer with 3+ years of experience developing smart devices. I specialize in firmware development using ESP32 (preferably with ESP-IDF), STM32, and TI C2000, with a strong focus on C/C++ programming, sensor integration, Modbus communication, and IoT performance optimization. I help turn complex hardware problems into reliable, scalable solutions — whether it’s custom firmware, OTA updates, or embedded web interfaces. Let’s bring your electronics project to life.
