Developed modular, non-blocking firmware for STM32 and ESP32 using ISRs, state logic, and fault-recovery mechanisms, integrating sensors and communication interfaces. Worked with SPI, I2C, UART, RS485, BLE, Wi-Fi, and LoRa/LoRaWAN, with exposure to Ethernet, MQTT, USB, and OTA. Contributed to hardware design and PCB development for power electronics, motor drives, industrial control, communication, battery management, and instrumentation systems within mechanical and manufacturing constraints. Collaborated with cross-functional teams via prototype iterations, supporting component selection, schematic standardization, and shared CAD library development.

Configured Modbus communication on a WINTEC HMI for efficient data visualization. Integrated multiple Modbus sensors and meters using custom LabVIEW code to ensure accurate data collection. Prepared technical documentation explaining the apparatus specifications and technical details of work delivered.

Learned fundamentals of operations and maintenance of a hydropower station. Prepared and reviewed documents and reports for the Purchase and Disposal department. Visited repair and manufacturing facilities for distribution and power transformers.
