I worked as a Firmware Engineer developing embedded solutions for advanced hardware platforms. My work included contributing to an AI camera device based on ESP32-P4, implementing firmware features and system components in a Zephyr environment for STM32N6, and helping develop a desktop tool used for device interaction and debugging. This software combined features similar to an oscilloscope and serial terminal (like PuTTY), while also supporting multi-device communication inspired by Nordic development tools, enabling engineers to monitor, control, and debug multiple embedded devices simultaneously.

I worked as a Firmware Engineer developing embedded networking solutions for ESP32-based systems. My work focused on implementing OTA communication using MQTT for remote firmware updates and command transmission, as well as developing reliable Wi-Fi and Ethernet network control mechanisms. I built an asynchronous web server on the ESP32 to process commands in real time and implemented buffer-based command processing in C/C++ for efficient data handling. I also developed a local Wi-Fi server on a Raspberry Pi using WebSockets to enable low-latency communication with ESP32 devices and led a team in creating a web platform that allowed users to monitor and control devices through a simple interface.
