Project description:
"I’m building a dedicated Android VPN client and need a Kotlin developer who has shipped at least one VPN‐related app before. The project centres on three core features: a reliable kill switch that never leaks traffic, a clean selector for multiple server locations, and a smart auto-connect that triggers on startup or whenever the device joins an unsecured network.

User access must be protected, so you’ll wire in a secure authentication flow (email-password or token-based—whichever you’ve proven most stable) and keep the session management lightweight to minimise battery impact.

You’re free to leverage OpenVPN, WireGuard or your preferred tunnelling library so long as the final APK passes Android 13 requirements and Play Store VPN permissions. The codebase should be 100 % Kotlin, structured for future modular expansion and covered by basic unit tests for the networking layer.

Deliverable: a production-ready Android Studio project, signed debug APK, and a brief setup/readme so my in-house team can compile and release updates without hand-holding." (client-provided description)
