This may well be a habit inherited from my start in a very small organisation where I was in charge of anything electronic, regardless of how much it looked like a computer, but.... I find when I'm describing a project I've done to anyone outside the organisation (and quite often inside, too), I almost always use We automatically. I may have done it but I did it on behalf (and frequently under the direction) of the organisation - it is an achievement and an asset for the organisation and should be credited as such.
