Bondlayer Staging App

Building a "Player" for other apps is significantly more complex than building a standard app:

Dynamic Asset Loading: The app had to download and inject custom fonts, assets, and configurations on the fly.

Native Parity: It had to support every native module, camera, GPS, haptics without knowing in advance how the user would use them.

Performance: It needed to feel like a "real" installed app, not a web-view or a slow simulation.

No Pre-existing Roadmap: This was built before Expo Go existed; we had to solve the "Live Reload" and "Remote Configuration" challenges from scratch.

The Solution

• The "Player" Architecture (React Native Core)

• I architected the Staging App as a pre-compiled shell containing all possible native dependencies. When a user logged in, the app would:

  Fetch a JSON-based manifest of their Bondlayer project via REST.

  Dynamically map that manifest to React Native components and logic.

  Trigger a "hot-swap" of the UI, transforming the empty shell into the user's custom application in seconds.

• Custom Native Extensions

• To ensure a true native experience, I built custom bridges for:

  Dynamic Font Injection: Allowing users to preview their brand’s specific typography without re-compiling the binary.

  Feature Simulation: Full access to the device's hardware (Camera, Geolocation, Accelerometer) as defined in the Bondlayer editor.

  Deep Linking & Navigation: A custom routing engine that could handle complex, user-defined navigation patterns dynamically.

• The Developer Experience (DX)

• I implemented a "Shake to Refresh" and "Instant Sync" workflow. As users made changes in the web-based Bondlayer editor, those changes were pushed to the Staging App via WebSockets, providing a live-preview experience that was years ahead of its time for the Portuguese market.

  The Impact Conversion Power: Transformed the sales process by allowing potential clients to see their own brand "live" on their phone within minutes.

  Reduced Support Burden: Allowed users to catch UI/UX errors in a native environment before the high-stakes App Store submission process.

  Technological Pioneer: Successfully delivered a "Play Store for your own apps" logic that anticipated the industry shift toward platforms like Expo.

  Technical Highlights Core Tech: React Native, Node.js (Manifest API), WebSocket (Live Sync).

  Native Bridges: Custom Java (Android) and Objective-C (iOS) modules for dynamic asset handling.

  Logic: Dynamic Component Mapping, Remote Font Loading, and State Hydration.
