Project: TrackerGuru

TrackerGuru is a desktop address book application for property agents managing large client portfolios. It features a Command Line Interface (CLI) optimized for fast typists with a JavaFX GUI. Written in Java with ~10,000 LoC.

Given below are my contributions to the project.

  • New Feature: Tag Group Management System

    • What it does: Allows creation and management of tag groups (e.g., propertyType, priceRange) to organize tags in GROUP.VALUE format (e.g., propertyType.HDB).
    • Justification: Property agents need to categorize contacts across multiple dimensions. This provides structured organization preventing tag proliferation and maintaining consistency.
    • Highlights: Implemented two-tier architecture with Tag and TagGroup classes, flexible validation (GROUP names alphanumeric, VALUE supports .-_ for real-world data like price.1.5M-2M), safeguards preventing deletion of in-use groups, full JSON persistence, and command suite (tg, dtg, ltg).

  • Code contributed: RepoSense link

    • ~2,196 total lines: 594 functional code, 1,127 test code, 474 documentation

  • Project management:

    • Created and managed 31 pull requests with comprehensive descriptions
