About

Who I am

I'm an AI & Data Science undergraduate at the Informatics Institute of Technology, affiliated with Robert Gordon University, UK - currently in my final year.

My work lives at the intersection of machine learning, data engineering, and computer vision. I enjoy turning complex, unstructured data into systems that actually do something useful.

Outside of tech, I'm a member of the Rotaract Club, the Data Analytics Society, and the Women in Engineering Society at IIT - and I play basketball for the university team.
