about

I'm Abby, a Computer Science student who has a habit of turning random ideas into actual products.

Most of what I build starts as a problem I keep running into myself, a coffee I forgot the name of, a revision list that never quite told me what to study next. I'd rather ship a rough version of that idea than leave it as a note in my phone.

I study Computer Science at Queen's University Belfast, I'm currently gaining professional technology experience, and outside of coursework I split my time between product design, writing code, and figuring out how to get the two to agree with each other.
