Project: E-lister

E-Lister is a desktop address book application used for streamlining contact management in insurance companies. The user interacts with it using a CLI, and it has a GUI created with JavaFX. It is written in Java, and has about 10 kLoC.

Given below are my contributions to the project.

  • Feature I: Added the export command.
    • What it does: Exports the data into a csv file at a location selected by the user.
    • Justification: This feature provides a convenient way for insurance agents to mass extract contact information such as email and phone number.
    • Highlights: This feature required the implementation of new helper classes to convert Person objects into csv-friendly text outputs.
    • Additional info: There are two optional keywords that can be appended to this command, namely all and shown.
      • all exports all contacts on the app
      • shown exports only contacts which are displayed, which is useful when the agent wants to target a specific group of potential customers
  • Feature II: Added the import command.
    • What it does: Imports the data from a csv file selected by the user.
    • Justification: This feature provides allows insurance agents to directly work on an existing dataset rather than adding contacts one by one.
    • Highlights: This feature required the implementation of new helper classes to parse csv inputs into instances of Person.
    • Additional info: There are two optional keywords that can be appended to this command, namely combine and reset.
      • combine merges the imported dataset with the existing contacts to preserve information while ensuring duplicates are ignored
      • reset removes all existing data and allows the user to start fresh from his/her dataset

  • Code contributed: RepoSense link

  • Project management:
    • Ensured the harmonisation of different features in solving the needs of our target users
    • Adviced and assisted feature design and debugging
    • Managed milestone progress and ensured tasks were completed on time
  • Enhancements to existing features:
    • Ideation and design of UI enhancements, including the tags and history panes
    • Refactored multiple classes and comments to match the E-Lister name
  • Documentation:
    • User Guide:
      • Added documentation for own features
      • Addition of various screenshots with labelled pointers to aid user navigation
    • Developer Guide:
      • Added implementation for import and export features
      • Added information on CSV-format conversion
      • Added ExportSequenceDiagram.puml to illustrate the export command process
      • Updated UML diagrams such as StorageClassDiagram.puml
