Project: TrAcker

TrAcker - TrAcker is a desktop event management application for NUS CS2040 Teaching Assitants (TA). The user interacts with it using a CLI, and it has a GUI created with JavaFX. It is written in Java.

Given below are my contributions to the project.

  • New Feature: Added the ability to filter students depending on their performance level and/or urgency level
    • What it does: Filters the students with lower performance or higher urgency than a threshold specified by the user
    • Justification: This feature improves the product significantly because the user can see the students who are currently struggling, in a very short time
    • Highlights: This enhancement is challenging because it affects the visibility of the different roles in our databases, without mutating the lists so that the execution of other commands can still allow all the other rows to be seen
  • New Feature: Added the ability to sort students in all groups by their particulars
    • What it does: Sorts the students in the specified group, according to a specified metric such as name, email, address, remark or performance level
    • Justification: This feature helps in attendance taking, or when the user wishes to view students who are performing weaker/stronger than their peers when recommending them for teaching assistant positions, or when deciding who to focus their attention to
    • Highlights: This enhancement is challenging because it should not mutate the list in a way that removes the original ordering, so that other commands can sitll function as expected. The avatar icons of each user in each group should also be ordered for better user experience when this command is executed.
