Context

FiberVPN provides secure network access across mobile devices. The app shows connection state, location switching, premium upsell, and subscription options.

The problem: The app needed a stable, cross-platform VPN experience with clear connection states and a subscription flow that converted free users.

Team & Ownership

Worked with the mobile team to integrate the VPN UI with platform tunnel extensions.

I built the Flutter UI, connection-state screens, and subscription flow. The native tunnel implementations were handled by platform specialists.

Challenges

• —Keeping Flutter UI in sync with native VPN connection state.
• —Handling platform-specific subscription lifecycles.
• —Presenting clear error states when the tunnel fails.

Key Contributions

• —Implemented location selection and connection-state screens.
• —Built premium upgrade and subscription prompt flows.
• —Connected Flutter state to native VPN events.

Key decisions

Results

• —Published on Play Store and App Store.
• —Implemented subscription-ready UI used in production.

Lessons Learned

• —VPN apps require tight coordination between native extensions and Flutter UI.
• —Subscription state needs careful handling around store restore and errors.
