Solitaire (Classic)

Solitaire (Classic) — competitive solitaire card game where users play for cash prizes through tournaments, head-to-head matches, and daily challenges, powered by the PROVEIT platform.

Technical info:

• Written in Swift, Storyboard-based UIKit architecture (~343 source files)
• MVC/MVVM hybrid — struct-based models, custom ViewController base class, singleton managers (Store, CurrentGame, UserData)
• Custom game engine — CALayer-based card rendering, undo/redo with move history, score calculation with time bonuses, game state snapshots
• ProveItSDK — internal SDK namespace abstracting tournament system, multiplayer matchmaking, leaderboards, and real-money transactions
• 4 build targets — localhost, sandbox, staging, production — each with its own Info.plist configuration
• Alamofire networking with AES-encrypted JSON API communication via custom Decrypter layer
• In-App Purchases (StoreKit) + Google AdMob for monetization
• SwiftLocation for state-based gameplay compliance and location verification
• Analytics: Firebase, Mixpanel, AppsFlyer; crash reporting via Fabric/Crashlytics
• Facebook SDK for social login; RNCryptor (AES) + SAMKeychain for secure storage
• Push notifications, jailbreak detection, device fingerprinting
• Deployment target: iOS 10.0+, iPhone and iPad supported

My role:

• Design app architecture and build from scratch
• Implement the networking layer with REST API and encrypted communication
• Pull requests and code reviews
