Quek Wei Ping - Project Portfolio

PROJECT: MooLah

Overview

This portfolio aims to document my contributions to MooLah

My team of 4 Computer Science students and I were tasked with enhancing a basic Command Line Interface desktop application AddressBook - Level 3 for our Software Engineering project. Over 6 weeks, we chose to morph it into a finance tracker application called MooLah. This enhanced application allows the typical NUS student to manage past expenses with the use of budgets, reminders for future expenses, helpful statistics and user-friendly input formats. It is written in Java, and has about 23k LoC. My main developer responsibility in the team consists of the statistics features across every component.

Summary of contributions

  • Big feature: I have added the ability to generate statistics in MooLah

    • What it does: This features consists of a basic summary of expenses, a side-to-side comparison as well as a trend analysis across different periods of time.

    • Justification: This feature improves the product significantly because the lack of analytic tools to make sense of data is a potential reasons for the problem of poor spending habits to be snowballed. The inclusion of a statistics feature addresses this directly, with varying levels of depths and visual representation the user can choose from.

    • Highlights: As the feature is closely coupled to the budget features and requires to support other dependencies such as undo/redo, constant coordination with other developers is required.

  • Code contributed: (Link to RepoSense)

  • Other contributions:

    • Project management:

      • Initiated the renaming of the product to MooLah

      • Reviewed pull requests of team mates

      • Facilitated meetings every Wednesday and Friday and consolidated discussion minutes,

      • Scheduled milestone tasks and ensure that project deliverables are completed on time in the right format.

      • Wrote additional tests for existing features to increase coverage from 52% to 59% (PR #254)

    • Enhancements to existing features:

      • Refactored Tag classes from AddressBook - Level 3 to Category class (PR #100, #129)

      • Populated SampleDataUtil class with various budgets and expenses so that MooLah has sufficient data upon first launch (PR #254)

    • Documentation:

      • Documented new statistics features in User Guide

      • Added the implementation of Statistics in Developer’s Guide

Contributions to the User Guide

We had to update the original AddressBook - Level 3 with instruction for the enhancement that we have added. The following is an excerpt from our MooLah User Guide, showing additions that I have made for the Statistics features.

Contributions to the Developer Guide

The following section shows my additions to the MooLah Developer Guide for the Statistics features. They showcase my ability to write technical documentation and the technical depth of my contributions to the project.
