Project: Steering Column Control Module (SCCM) for automotive systems using ARM Cortex-M4 MCUs. Key Achievements & Skills: As an Embedded Software Engineer at ZF TRW Automotive, I contributed to the development of the Steering Column Control Module (SCCM) for automotive systems using ARM Cortex-M4 microcontrollers. I developed over 10 embedded firmware modules in Embedded C, achieving sub-2ms task switching latency with FreeRTOS. I integrated the CAN communication stack using Vector GENy, reducing response time by 25%, and optimized real-time performance through CPU profiling and trace analysis using WinIDEA and iSystem IC5000. I also implemented cybersecurity features using CycurLIB on S32K MCUs to ensure compliance with ISO 21434 standards. In collaboration with hardware and test teams, I led system validation using CANoe and VT System across more than 30 test cases, boosting test coverage to 95%. I managed requirements using IBM DOORS and maintained 100% traceability of issues using MKS Integrity and ClearQuest.

Project: SoC validation using PSoC5 microcontrollers for analog/digital signal processing. Key Achievements & Skills: As a Firmware Engineer at Sasken Technologies, I worked on embedded firmware development and validation for high-precision automation systems based on PSoC5 microcontrollers. I developed firmware for USB, I2C, and SPI communication protocols, achieving 99.8% data integrity in validation testing. I automated more than 40 test scripts in C/C++ for protocol-level testing, which reduced manual effort by 60%. I led USB compliance and interoperability testing using USB CV and HSETT tools, ensuring full certification readiness. I also integrated BLE and Wi-Fi modules on ARM Cortex-M3 platforms, improving wireless performance by 30%. Additionally, I utilized Keil µVision IDE to configure DMA channels and optimize peripheral access latency by 12%.

Project: USB 2.0 Subsystem validation using Synopsys DWC_OTG controller with M7450 modem. Key Achievements & Skills: As an Embedded Engineer at Sasken Technologies, I was responsible for validating the USB 2.0 subsystem using the Synopsys DWC_OTG controller on the M7450 modem platform. I diagnosed and resolved over 50 complex defects in the USB device stack and ACM/NCM class drivers, significantly improving subsystem stability. I performed crash dump and trace log analysis using Lauterbach Trace32, which reduced debugging time by 40%. I also developed functional test plans for ULPI and HSIC interfaces, achieving 100% test execution across multiple system variants. By working closely with the chip integration team, I helped reduce regression failures by 25% and ensured consistent USB functionality across various configurations.
