Hello!
I am a software developer with expertise in both front-end and back-end technologies. I hold a Master’s degree in Information Systems from Friedrich Alexander University of Erlangen-Nuremberg, where I developed a strong foundation in software engineering concepts, blending both theoretical knowledge and hands-on experience. My journey into technology began after earning a Bachelor's degree in Business Economics from the University of Colombo in 2018. I initially worked as a Management Information Systems Analyst at Moody’s Analytics Knowledge Services in Sri Lanka for two years, where I gained valuable experience in data-driven decision-making and business intelligence. Driven by my passion for software development, I transitioned into the field through my Master’s studies, focusing on advanced software engineering techniques and emerging technologies. During my academic and professional journey, I have worked extensively with Large Language Models (LLMs) and conducted research on cutting-edge methodologies to enhance Retrieval-Augmented Generation (RAG) systems. My thesis focused on improving retrieval efficiency and response quality in RAG pipelines using advanced re-ranking models. I am passionate about building scalable and intelligent software solutions, leveraging AI-driven approaches to optimize information retrieval and user experience..

"Enhancing Retrieval-Augmented Generation Pipelines for Improved Performance: A Comparative Analysis of Reranking Models." The project focuses on evaluating the impact of different reranking models in Retrieval-Augmented Generation (RAG) pipelines, using varying configurations for initial retrieval (k).
Chatbot project developed for the FAU website using the Cognigy coding platform. The main use case was a new student joining the university and going on about her issues when getting relavant information from FAU website and its different kinds of portals. This chatbot will address different student needs related to their program structure, accommodation, transport, health insurance or so by providing reliable answers from FAU databases.
