About Me

I'm a final-year Electronic and Telecommunication Engineering undergraduate at the University of Moratuwa, Sri Lanka (CGPA: 3.63/4.00), specializing in RF/Microwave Engineering, RFIC design, and Antenna Systems.

I gained industry experience as an Embedded Systems Engineering Intern at Paraqum Technologies and later as a Part-Time Electronic Engineer at Sentranova (March-September 2025), working on RF solutions, hardware design, and system integration.

Currently, I'm focused on my final-year project and research in RF/microwave circuits, IC layout, and wireless systems, turning complex challenges into high-performance engineering solutions.
