I work as an IoT Engineer, developing and implementing embedded and IoT-based solutions using microcontrollers such as Arduino, ESP32, and other embedded platforms. My role involves designing hardware systems, developing firmware, integrating sensors and actuators, and building automated monitoring and control systems for real-world applications. In my daily work, I design and prototype IoT devices that collect data from various sensors such as temperature, humidity, gas, pressure, and motion sensors. I develop embedded software in Arduino C/C++ to control devices, manage sensor data, and implement automation logic. I also work on integrating displays such as LCD and OLED screens to provide real-time system information. I am responsible for circuit design, component selection, PCB prototyping, and system testing to ensure reliable hardware performance. Additionally, I implement communication protocols such as WiFi, Bluetooth, and serial communication to enable data transmission between devices and cloud platforms. My work includes debugging hardware and firmware issues, optimizing embedded systems for efficiency and reliability, and developing automation systems for industrial and research applications. I frequently build systems that perform timed operations, sensor-based decision making, and real-time monitoring. I collaborate with engineering teams to design scalable IoT solutions, document system architecture, and ensure that products meet functional and performance requirements. Through my work, I contribute to the development of smart systems that improve efficiency, monitoring, and automation in various applications.
