Conducted R&D and cross-analysis of emerging display technologies including TDDI, focusing on capacitive sensing performance and low-power embedded systems. Built automated Python test pipeline interfacing a 6-axis robotic arm to evaluate TDDI touch KPIs (sensitivity, linearity, SNR) reducing manual test time by ~40%. Designed analog signal conditioning circuits for capacitive touch sensing (I2C/SPI interface/UART), contributing to hardware–software co-design and achieving reliable SNR performance.

Developed bare-metal C firmware for STM32 Nucleo (ARM Cortex-M) to manage Power Distribution Units (PDU) in BEV zonal architecture, including CAN/SPI/UART interface drivers, flash parameter storage, and hardware-in-the-loop test bench validation. Developed and executed test cases for PDU validation on STM32 Nucleo and hardware-in-the-loop (HIL) test bench, verifying correct electrical behaviour across BEV load profiles and fault conditions. Designed and optimised zonal Power Distribution Unit (PDU).

Migrated production firmware from Nordic nRF9160 (LTE-M/NB-IoT) to nRF52 BLE SoCs using Zephyr RTOS, implementing UART/SPI bridge protocols and reducing boot latency by ~15%. Developed Python automation tooling for firmware flashing and remote device management; optimised real-time embedded applications using Zephyr RTOS with MQTT-based telemetry for IoT sensor data reporting. Debugged embedded Linux systems on Raspberry Pi 3/4 using JTAG, GDB, and serial console; performed remote diagnostics with SSH.

Developed Python automation scripts and macro tooling to streamline electrical network configuration workflows, cutting manual processing time by ~25%. Provided Technical support to customers regarding Electrical Networking-related issues. Debugged analog and digital electrical circuits using oscilloscope, multimeter, and bench power supply on breadboard and PCB, identifying, and resolving signal integrity faults.

Programmed ESP32 microcontroller in C on Arduino framework for IoT hardware deployment; developed automated test cases for production validation. Troubleshot IoT hardware circuitry faults using oscilloscope and multimeter, resolving signal integrity and power rail issues to restore full device functionality. Implemented HTTP/REST and MQTT communication on ESP32 to transmit RFID data over Wi-Fi to cloud endpoint, enabling real-time remote monitoring and access-control event logging.
