Serverless Image Processing Pipeline
S3 uploads trigger resizing, thumbnails and moderation automatically
2-3 weeks build
Overview
An event-driven pipeline with nothing running between uploads. A browser uploads straight to S3 through a presigned URL, the upload event triggers a Lambda that produces resized and WebP versions, and a moderation step asks Rekognition for unsafe-content labels before an image is published. Failures land in a dead-letter queue instead of vanishing, and at demo volumes it stays inside free-tier limits.
What makes it stand up
- 01Direct browser-to-S3 uploads with short-lived presigned URLs
- 02Resized, thumbnail and WebP variants generated on upload
- 03Moderation labels checked before an image goes public
- 04Dead-letter queue and retries for uploads that fail processing
- 05Image metadata and moderation status stored in DynamoDB
Module breakdown
- 01
Upload
Presigned URL endpoint and a simple web uploader.
- 02
Processing
Pillow Lambda that writes each variant to an output bucket.
- 03
Moderation
Rekognition labels with a threshold and a review queue.
- 04
Metadata
DynamoDB records for sizes, status and processing time.
- 05
Reliability
Retries, a dead-letter queue and recursion-safe bucket layout.
After this, you will be able to
- Explain event-driven design and why the output bucket is separate
- Defend your failure handling and retry strategy
- Demo an upload turning into thumbnails within seconds
