At LG Soft India, I build production firmware for smart washing machines, including Wi-Fi connectivity with Android apps for remote control, diagnostics, and machine-status monitoring.
I designed a layered, Linux-inspired firmware architecture using Embedded C, FreeRTOS, Zephyr, DeviceTree, and UART, separating hardware abstraction, platform services, and application logic. I also created a Python desktop tool for protocol packet testing and serial communication debugging.
Previously at Quantum Power System, I customized Linux and Android kernel drivers, brought up Qualcomm-based boards, and built Yocto-based Embedded Linux systems for electronic ticket machines. My work spans C/C++, Linux kernel, device drivers, BSP customization, MIPI interfaces, UART, SPI, I2C, MQTT, and real-time firmware validation.
