Current Projects ✨

Here's what I'm working on, from my day-to-day university program to my currently active side projects.

MSc Artificial Intelligence

I just finished my MSc in Artificial Intelligence at the University of Edinburgh, where I rowed in the EUBC Rec crew. The MSc consisted of two semesters of coursework, followed by a thesis project during the summer. For my thesis, I was at Adyen in Amsterdam, working on transfer learning for credit card fraud prediction models.
