Joan Kuberan Jesu Ratnam

Owned the automation of the diagnostic module for Inductive Charging (Wireless Power Transfer) systems using Python and UDS Performed CAN trace analysis using CANoe and CAPL to investigate root causes of hardware-software interaction defects Automated validation workflows to optimize testing of power electronics and communication interfaces Supported system qualification and integration testing of high-voltage WPT systems in an EV charging environment

ADAS Requirements Engineering (Continental programme): Supported requirements engineering for an ADAS driver assistance programme during the first 6 months, applying structured elicitation and traceability practices to camera based driver-assistance functions. Managed software requirements for safety-critical Chassis Control systems. Defined functional descriptions and architectural use cases in SystemWeaver and DOORS. Ensured 100% requirements-to-test traceability for high-integrity mechatronic systems

Directed integration test activities and software releases for ADAS systems, ensuring compliance with ASIL-B and ASPICE audits Executed unit testing using VCAST for embedded software modules, ensuring code coverage and functional correctness at module level Automated complex integration test cases with vTestStudio to improve silicon-level validation efficiency Managed cross-functional technical alignments between design, hardware, and development teams using Jira for defect tracking and project coordination

Driver Development: Designed and implemented AUTOSAR Complex Device Drivers (CDD) for Debug Services, System Timer Managers, and Power Managers. Safety Analysis: Conducted ISO 26262 safety analysis (FMEA & FTA) at ASIL-D module level for semiconductor-level drivers. Automated tool updates for AUTOSAR code generation using Perl scripts.

• Platform Integration: Led software integration for Audi and VW engine controllers utilizing MPC5746r microcontrollers. • System Verification: Performed comprehensive HIL tests over Labcar (ETAS) and quality checks prior to silicon-to-OEM delivery. • Resolved complex module dependencies for final package development in high-volume production environments.
