- Built a Python Robot Framework library for IO-Link master validation, and automating regression testing - Developed a pysoem-based EtherCAT–IO-Link test library with custom AoE support for automated cross-stack fieldbus validation - Wrote Lua-based Wireshark dissectors for IO-Link SMI, AoE, and CoE, enabling packet-level protocol debugging - Designed a hardware root-of-trust authentication system (ATECC608 + STM32G431RB) with X.509 certificate hierarchy and ECDSA device authentication - Integrated an IO

- Covered AUTOSAR architecture (HSM core, application layers, COM stack), RTOS fundamentals, ARM Cortex-Mx (MPU, FPU, MMU), embedded communication protocols (UART, SPI, I2C, CAN, LIN), and Agile testing methodology.

- Implemented Modbus RTU communication in Python between a particle sensor, pump, and alarm system, resolving integration issues and improving end-to-end data consistency. - Conducted system-level testing and debugging across 3 hardware components, identifying and correcting 4 communication edge cases prior to deployment.
