About
I am an Electrical and Electronics Engineering student focused on Embedded Systems, IoT, Smart Energy Technologies, and Industrial Automation — turning real-world engineering problems into reliable, scalable solutions.
I work at the intersection of hardware, software, and energy systems. My experience spans designing sensor-driven automation systems, building IoT-based control platforms, and developing renewable-energy solutions including solar-powered dewatering systems and automated monitoring platforms.
Through industrial training at Coromandel International Limited, I built a strong foundation in power systems, electrical machines, control systems, and industrial maintenance.
