The Journey
I created a robust serverless backend using Firebase Cloud Functions, integrated with AI capabilities and image processing, all exposed through a standardized oData API gateway.
Technical Implementation
Function Architecture
- Storage trigger for image processing pipeline
- Authentication middleware for AI chat access
- RESTful endpoints following oData standards
- Proxy configuration for public access
Image Processing Pipeline
- Storage bucket change detection
- Multi-format image conversion
- Automated metadata extraction
- Firestore document creation
