About Me

Hi, I’m Ellie 👋

I’m a First Class BSc Computer Science Graduate from the University of Exeter, passionate about software development, reverse engineering, and data analysis.

Since much of my work involves reverse engineering, I can’t always post full source code; but here are a few of my key projects with detailed write-ups.
