Steve delivered a security-focused overhaul of the authentication flow for the Spawn-App-iOS-SwiftUI repository, building a robust, token-based session lifecycle for iOS using Swift and SwiftUI. He implemented persistent storage of access and refresh tokens, along with external user IDs, leveraging Keychain Services to maintain user sessions across app restarts. His approach included a resilient token refresh mechanism triggered by 401 responses, automatic sign-out on refresh failure, and secure credential clearing during logout or account deletion. By ensuring access tokens were sent only when necessary, Steve reduced credential exposure, demonstrating depth in API integration, authentication, and secure session management within mobile applications.

In April 2025, delivered a security- and reliability-focused overhaul of the Spawn App iOS (SwiftUI) authentication flow. The enhancements create a robust, token-based session lifecycle with secure storage, resilient refresh logic, and hardened logout, aligned with reducing sign-in friction and improving security across sessions.
