About Me

Hello,

I'm a software engineer from the south of Oxfordshire, developing web applications for the cloud and focusing on backend. I build performant and maintainable systems, and enjoy helping colleagues do the same. Here I am pictured in a ball pit, but for work purposes I am usually sat at a desk.
