I currently finish my bachelor thesis in computer science. And sometimes I wonder if I write too personal, since my thesis should be an academic piece.

More specific, I wrote a computer program (which has no name at the moment) and I often don't know how to refer to that program and me working on that program.
Can I say something like: "My program consists of two parts ...", or "I implemented a function that does ..."?
Or should I be always completely objective and say "The program of this thesis consists of two parts..." and "The program of this thesis has a function that does ...", which feels a bit counterintuitive.
