Build guide

1. 01Scaffold the Go Backend API

   Initialize a modular Go project with a clean architecture layout. Implement database migrations for users, files, metadata, and sharing tokens using PostgreSQL.

   Create a new Go backend project using Chi or Gin router. Set up a PostgreSQL database connection pool using pgx. Implement database models and migrations for users (id, email, password_hash, master_key_salt), files (id, user_id, encrypted_metadata, size, checksum, storage_path, created_at), and albums. Include structured JSON logging, graceful shutdown, and a health check endpoint. Write comprehensive unit tests for user registration and file metadata record creation.

2. 02Implement S3-Compatible Storage Integration

   Add an abstraction layer in the Go backend to stream encrypted file chunks directly to an S3-compatible bucket (such as Backblaze B2 or local MinIO for development).

   Add an object storage service package to the Go backend using the official AWS SDK for Go v2. Implement methods to generate presigned upload and download URLs, handle multipart streaming for large encrypted video files, and delete file objects securely from the bucket. Ensure the service supports configurable S3-compatible endpoints for Backblaze B2 or self-hosted S3 storage.

3. 03Build Client-Side Encryption Core (Flutter)

   Develop the cryptographic utility module in Flutter using point-to-point encryption primitives. Ensure keys are derived securely and never transmitted to the server in plaintext.

   Create a Dart cryptographic module using point-to-point encryption libraries. Implement key derivation functions (PBKDF2/Argon2) to generate a client-side master key from user passphrases. Implement authenticated encryption (AES-GCM) for encrypting local file bytes and JSON metadata structures before upload, along with corresponding decryption routines for downloads. Write unit tests verifying that zero plaintext metadata or master keys escape the client boundary.

4. 04Construct Flutter Cross-Platform Client Shell & Gallery Grid

   Set up the multi-platform Flutter app structure with state management, secure local storage for keys, and a high-performance virtualized media grid view.

   Scaffold a Flutter cross-platform mobile application supporting iOS and Android. Implement state management using Riverpod or Bloc. Set up secure local storage (flutter_secure_storage) for holding client encryption keys. Create a responsive photo gallery grid view with local caching and thumbnail lazy-loading using custom photo manager plugins to ensure smooth scrolling performance over thousands of local items.

5. 05Implement Background Upload Daemon

   Build a reliable background service daemon in Flutter that monitors local device asset changes and pushes encrypted chunks to the Go backend API.

   Implement a background service worker in Flutter (using workmanager or native platform background fetch APIs) that periodically checks for new local media assets. The worker must fetch unbacked-up local items, read file bytes, encrypt them using the client-side encryption module, upload chunks to the Go backend API with retry backoff logic, and update local synchronization state tables.

6. 06Build Album Sharing and Public Links

   Add backend routes and client UI for creating shared albums and public cryptographic view links with granular permissions.

   Implement album sharing logic in the Go backend allowing users to create collaborative albums and grant access tokens to other users or generate public view links. Add endpoints for sharing encrypted file keys re-encrypted for recipient public keys. In the Flutter client, add UI screens for viewing shared albums, accepting invitations, and rendering decrypted shared media items seamlessly.

7. 07Containerize and Deploy Infrastructure

   Dockerize the Go backend service and deploy it alongside a PostgreSQL database instance to Fly.io, configuring environment variables and reverse proxy routing.

   Create a multi-stage Dockerfile for the Go backend application ensuring a minimal production image size. Write a fly.toml configuration file for deployment on Fly.io, including persistent volume mounts for local assets if needed, environment variables for S3 credentials, database connection strings, and secret keys. Document environment setup and deployment steps in a clear README.
