Christine’s Status Report for 3/22

✅ Progress This Week

• Finished the initial implementation of the match upload layer (PR Link)
  This layer handles the ingestion, processing, and storage of detected license plate matches. The flow is as follows:

  • Dash cams upload images via pre-signed S3 URLs

  • An S3 event triggers a Lambda function to:

    • Extract GPS and timestamp metadata from image EXIF

    • Store the metadata in the match_logs table in DynamoDB

  • Architecture: S3 → S3 Event → Lambda → DynamoDB (match_logs)

• Documented the full flow in the PR description, covering:

  • Pre-signed URL generation

  • Upload handling via S3 and Lambda

  • Metadata extraction and logging

  • All changes are fully covered by tests

This gives a scalable and decoupled foundation for matching plates to images and metadata.

🚧 What I’m Working on Next Week

• Dash Cam Integration

  • Begin integrating the new match upload layer with the dash cam system

  • Revisit existing endpoints (/detections, S3 upload) to determine required changes

  • Prioritize approaches that minimize friction for the dash cam side

  • Coordinate with others for schema consistency across services

• Observability Improvements

  • Expand CloudWatch logging:

    • Currently tracks S3 and Lambda activity

    • Will add API Gateway request logs, performance metrics, and error tracking

  • Goal: improve visibility into API usage, failure rates, and overall latency

📌 Overall Status

Currently on track. The core functionality for match upload is complete and tested. Integration with the dash cam system will be the main challenge next week.
