User Stories
Sometime in second semester last year, I had to design and document a set of user stories, and then present it in the form of a user story map. Documenting user stories is a fairly common task in the information technology world especially when dealing with projects. User story maps, and user story visualisation techniques, however, are more difficult to structure and create - there is by and large a lack of free and open source software to do this sort of thing, and do it nicely.
So, being the occasionally rational chap that I am, I wrote a simple little web app (that has no persistence currently) in AngularJS that creates user stories for you.
Whilst simple, it is these little projects that help you out and are incredibly satisfying for the amount of effort which they take to complete.
