Developed embedded firmware for Lenovo ThinkPad audio, docking, and peripheral subsystems using ARM Cortex-M, integrating SPI, I2C, and UART drivers. Re-architected the Lenovo Embedded Controller and power management components with modular C/C++ and FreeRTOS, improving stability and enabling secure OTA updates via Jenkins-based CI/CD. Performed hardware-in-the-loop debugging using JTAG/J-Link/TRACE32 and lab tools to reduce defects, and integrated telemetry diagnostics through embedded Linux services. Automated log analysis using ELK, Splunk, and Python to speed root-cause investigations.

Built an industrial IoT sensor node platform on Broadcom BCM Cortex-A with embedded Linux, integrating SPI/I2C sensors for real-time monitoring. Implemented a Linux communication stack for sensor-to-gateway connectivity using Ethernet and MQTT over TCP/IP, improving reliability and telemetry latency. Developed Linux kernel drivers and user-space interfaces for data acquisition and peripheral control, optimizing interrupt handling and DMA to support high uptime. Debugged and validated communication paths using JTAG/GDB and Wireshark, ensuring stable behavior in production-like deployments.
