I'm a Computer Science and Engineering student at the Rajshahi University of Engineering & Technology (RUET). Furthermore, I am a competitive programmer and a freelancer. Working with Arduino and embedded systems is something I'm passionate about. A mechanical ventilator project launched my career in this industry. After that, I worked on several Arduino, ESP8266, and ESP32 projects. I've worked with Arduino-based systems for two years. I have completed several mega projects, including an automatic Ambu bag-based medical ventilator, bee-hive monitoring, and controlling system, a CPAP-BiPAP ventilator, an environmental pollution monitoring system, an IoT-based soil moisture monitoring and controlling system, and an IoT-based dog tracking system, to name a few. Apart from that, I can create Android and Web applications. I've previously worked on Android apps like Bluetooth-based ventilator monitoring and control, BLE-based distance measurement systems, WiFi-based home automation apps, and web apps like IoT-based dog tracker projects. I've worked with Android apps using Java and Flutter before. I'm currently working on machine learning with TensorFlow.
