I love reading ads like this. It reminds me of learning algebra in school: taking something like ab = a(c-1) and reducing it to b=c-1. Its a concept we use in programming everyday: refactor and reduce until unnecessary variables/work is removed.
Ads written for development positions by non-developers take the opposite approach. They take a word from the title, ie developer (a) and then use a thesaurus to expand it to ab=defghijkl(c-1). I once had a job description sent to me where being able to read was a requirement (next to having advanced qualifications).
Not criticism, just struck by how much I want to give ads like this to a mathematician with a pencil and say: enjoy 🙂
