About
I am a Computer Science undergraduate at the University of Colombo School of Computing with a deep passion for Natural Language Processing and Explainable AI (XAI). My work bridges the gap between rigorous research and scalable software engineering.
Currently, I am investigating explainability mechanisms in neural summarization models, specifically using Knowledge Graphs to validate factual consistency. I've also co-authored published research on SinhalaMMLU, a benchmark for evaluating LLMs on multitask language understanding for the Sinhala language.
When I'm not diving into transformer architectures or fine-tuning models, I enjoy building robust web applications using React, Spring Boot, and PostgreSQL. I believe that for AI to be truly impactful, it must be both efficient and understandable.
