About me

I care about how a product feels as much as how it works. I build responsive websites, cross-platform apps and interfaces that make complicated information easier to use.

I graduated from the University of Derby with a BSc in Computer Science in 2018 and have worked as a software engineer since. I enjoy collaborating with a team and taking ownership of a piece of work from idea through delivery.
