Hi I'm Andy Callaghan, a freelance Ruby developer from the UK. I live in York with my doctor wife Emily and golden dog, Freddy.

I have a passion for Ruby, code design, performance, algorithm design, rock drumming, and the Oxford comma.

I’m one half of Recollate, a software development agency.

I play drums for the York indie band Albany/Buffalo.

I also run CoderDojo York, free coding sessions for 7-17 year old young people in York.
