Pokédex Pro

A WPF-based Pokédex app demonstrating API integration

C# • WPF • XAML • API Fetch

C# Development

  • Built a Pokédex desktop application using WPF (C#)
  • Integrated the PokéAPI to dynamically fetch and display Pokémon data, including stats, types, and sprites.
  • Implemented stat calculation logic using base stats, EVs, IVs, level, and nature multipliers for accurate in-game results.
  • Added input validation and error handling for user-provided EVs, IVs, and level values.
  • Developed type mapping and nature modifiers for enhanced gameplay accuracy and data clarity.
  • Organized code into separate layers for UI, logic, and data parsing to ensure maintainability and scalability.
