Python script with hardcoded values needed a desktop GUI with editable fields, config persistence, and cross-platform deployment | Solution implements Tkinter-based interface with JSON config and PyInstaller builds

Developed a cross-platform GUI application to replace hardcoded values in a Python script with editable fields, persistent configuration via JSON, and single-file deployment using PyInstaller.

Issue

The original Python script suffered from:

  • Hardcoded values for job details and generation parameters, requiring manual code edits.
  • No persistence between sessions, forcing users to re-enter customizations.
  • Lack of a visual interface, relying solely on command-line usage.
  • Platform dependency, requiring Python installation on target machines.
  • No real-time feedback during document generation.

Culprit

  • Architectural limitations: Configuration mixed with business logic, no separation of concerns.
  • No state management: All values reset on script restart.
  • Single-threaded execution: No progress feedback or real-time updates.
  • Manual parameter passing: No structured way to handle complex inputs.
  • Path handling issues: Platform-specific compatibility problems.

Solution

  • Tkinter-Based GUI: Implemented a 4-tab interface for job, candidate, settings, and generation.
  • JSON Configuration: Added automatic serialization of user inputs for persistence.
  • Cross-Platform Deployment: Used PyInstaller to bundle the application into a single executable.
  • Real-Time Feedback: Added live logging and progress indicators during generation.

The solution provides a 100% backward-compatible GUI wrapper with no external dependencies beyond the standard library, supporting seamless cross-platform deployment and persistent user configurations.
