University of Moratuwa, Sri Lanka

Computer Science, MS•  January 2021 - Present

My post-graduate diploma specializes in Software Architecture and the key modules included Requirements Engineering, Big Data Analytics Technologies, Software Architecture Concepts, Advanced Databases, Human-Computer Interaction, Machine Learning, Software Quality, Rapid Application Development, Distributed Computing, Advanced Algorithms, Enterprise Software Architecture, E-Commerce and Software Process and Management. For my post-graduate diploma project, I surveyed precision agriculture through my research titled ”A Reliable Dense Sensor Network for Precision Agriculture.” Throughout this research, I surveyed LoRa and LoRaWAN technologies, the existing research works that investigate the key causes of packet loss in LoRaWAN networks, performance measurements of the packet loss ratio, and current solutions to reduce the packet loss ratio.

Faculty of Engineering, University of Ruhuna

Electrical Engineering & Computer Science, BS•  January 2016 - March 2020

During my bachelor's, I covered software engineering, electronics, telecommunication, and power domains, specializing in software engineering in my final year. Key modules included Signals and Systems, Computer Vision and Image Processing, Embedded Systems, Electronic Circuit Designs, Communication Systems, Control System Design, Intelligent Systems Design, Data Structures and Algorithms, Object Oriented Programming and Machine Learning. I engaged in research projects such as my final year project "Sleep Classification using XeThru Sensor" and "EO/IR Based Maritime Surveillance System". Additionally, embedded systems projects like the "Automatic Drug Injector" and "Fingerprint Attendance System" honed my hardware-software integration, real-time systems, and low-level programming skills. My passion for robotics led to active participation in competitions, securing notable positions.
