To create a flowchart like the one in your image, here’s how it can be laid out:

1. Top Level: User (Browser/Mobile App)

• Arrows leading to the Backend (Node.js + Express).

2. Middle Layer:

• Decision nodes like:

• “Is the user authenticated?”

• “Is the file processed?”

• “Is the capsule ready for delivery?”

3. Bottom Layer:

• Components like:

• Firestore (Data storage).

• Firebase Storage (Media storage).

• Notification Services (Push notifications and emails).
