About Me

Bridging electronic schematic design, firmware execution, and rigorous reliability validation.

I am an Electronics and Communication Engineering graduate with a strong foundation built through both polytechnic excellence (91.1%) and engineering studies (CGPA 7.9). My passion resides at the convergence of physical circuit layouts and real-time firmware execution.

Currently, I serve as a Graduate Apprentice Trainee in the Product Reliability Assurance Lab at Pricol Limited. My day-to-day focus centers on critical automotive instrumentation verification — conducting electrical transients, EMC immunity tests, ESD tolerance, and environmental stress screening on commercial cluster electronics.

Prior to this, during my developer internship at Pantech Solutions, I designed embedded C firmware, integrated multi-sensor suites, and resolved board-level hardware faults. Additionally, I have authored two published peer-reviewed research papers covering autonomous robotics and RFID security workflows.
