Mobile Security Coder

This is your go-to when you're writing mobile code that handles sensitive data or user authentication. It covers the practical stuff like WebView security configuration, proper keychain and keystore usage, certificate pinning, and biometric auth implementation. The skill distinguishes itself from general security auditing by focusing on hands-on coding rather than architecture reviews. What's useful here is the platform-specific guidance for both iOS and Android, plus coverage of cross-platform frameworks like React Native and Flutter. If you're implementing OAuth flows, securing local storage, or need to validate deep links properly, this gives you the patterns and practices without the theory dump.
