• Designed, developed, and integrated Embedded C software for automotive ECU applications, delivering communication, diagnostic, and performance enhancement features for commercial vehicle platforms.
• Implemented UDS (ISO 14229) diagnostic services, including ReadDataByIdentifier (0x22), ReadDTCInformation (0x19), and ClearDiagnosticInformation (0x14).
• Developed SAE J1979-2 diagnostic functionalities, including IUMPR, Readiness Groups, SMAD, proprietary PIDs, MIDs, and ITIDs.
• Designed and implemented SAE J1939 PGNs and SPNs, incorporating timeout monitoring, signal scaling, offset handling, signal validation, and variable broadcast rate communication.
• Developed custom End-to-End (E2E) communication protection using CRC validation and rolling counter verification to ensure reliable communication and data integrity between ECUs.
• Created and maintained OBDM files to support diagnostic communication, software validation, and production software releases.
• Optimized ECU performance by configuring MMU/TLB during boot-time initialization and enabling cache for non-DMA memory regions, improving processor utilization and memory access efficiency.
• Performed low-level debugging and memory validation using TRACE32 to verify memory mapping, cache configuration, and software behavior.
• Performed functional, integration, regression, and communication validation using PCAN, CANoe, Calterm, ScanTool, and UDS diagnostic test suites.
• Investigated software defects and diagnostic failures through root cause analysis, resolving communication issues, duplicate DTC reporting, and software integration problems.
• Supported software integration, code reviews, static code analysis, production issue investigation, and software releases throughout the Software Development Lifecycle (SDLC).
• Worked in an AUTOSAR Classic environment, supporting COM, DCM, DEM, and NvM modules while resolving Polyspace findings and ensuring MISRA-C compliance.
• Collaborated with cross-functional teams during requirement analysis, implementation, validation, integration, and production release activities, while contributing to the onboarding and technical enablement of new engineers.
