## What it is
The complete client and server source code for Viewfinder, a discontinued photo-sharing service, released after shutdown. It serves as a reference implementation covering a DynamoDB-backed server, iOS/Android apps, and mobile full-text search built on LevelDB.

## Use cases
- study how a startup built a DynamoDB-backed backend in Python
- learn to build a full-text search engine on top of LevelDB for mobile
- see how to detect duplicate photos using perceptual fingerprints
- reference for sharing code between iOS and Android with GYP
- revive or fork a photo-sharing app codebase
- learn database schema and indexing patterns on DynamoDB

## When to choose
- you want a real-world reference for mobile photo app architecture
- you need examples of DynamoDB schema design, indexing, and versioning
- you're interested in LevelDB-based mobile search or image fingerprinting

## When to avoid
- you need a maintained, supported photo-sharing service
- you expect clean, well-tested production code
- you need current iOS/Android toolchain compatibility

## Facets
- artifact type: application
- maturity: abandoned
- function: http-server, search-engine, image-processing, database, mobile-framework
- domain: mobile-development, backend, photography, databases, developer-tools
- platform: python, cross-platform
- tags: photo-sharing, dynamodb, leveldb, shut-down-service, reference-code, full-text-search, perceptual-hashing, ios, android
