AWS Cloud Album Project

Technology Stack

Python, Flask, AWS (EC2, S3, SQS, Lambda), SQL, YOLOv8 (ONNX), RESTful API, JWT, OpenStreetMap/Leaflet, HTML/CSS, Docker

Project Overview

Designed and implemented a cloud-native AI photo management system that enables scalable image storage, asynchronous processing, and intelligent organization through automated classification and metadata extraction. The system supports large-scale photo collections with efficient retrieval and location-based visualization.

Key Features

Intelligent Image Classification

• Integrated YOLOv8 (ONNX) for automated image classification with confidence scores
• Enabled metadata-driven search and structured organization of images

Asynchronous Processing Pipeline

• Designed an event-driven pipeline using SQS + Lambda
• Decoupled user requests from ML inference to improve system scalability and latency

Cloud Storage & Data Management

• Stored image assets in Amazon S3 and metadata in SQL database
• Designed schemas for users, images, labels, locations, and processing status

RESTful Backend Services

• Built Flask-based REST APIs for authentication, upload, retrieval, and album management
• Implemented JWT-based authentication and access control

Location-Based Visualization

• Extracted EXIF GPS metadata and visualized images via OpenStreetMap/Leaflet
• Enabled map-based browsing and filtering

User Interaction Enhancement

• Designed a follow-up metadata collection mechanism to improve search accuracy

System Architecture

• Frontend: HTML/CSS client for interaction
• Backend: Flask API deployed on EC2
• Async Layer: SQS (queue) + Lambda (workers)
• Storage: S3 (images) + SQL (metadata)
• ML: YOLOv8 inference via ONNX
• External: OpenStreetMap for geospatial rendering

Technical Contributions

• Built an end-to-end event-driven ML pipeline integrating storage, queue, and compute
• Designed scalable relational schema for metadata querying and status tracking
• Implemented asynchronous workflows to improve system throughput and reliability
• Enabled secure communication via HTTPS and IAM-based access control
