A backend engineering platform coordinating field operations across a nationwide campaign. ~200,000 voter and field records, three access tiers (admin, field agent, observer), and async processing for image and document workflows.
Challenges
Sensitive voter data with strict access control requirements.
Field operations generating large volumes of records and media.
Async processing for image analysis and document handling.
Approach
Laravel + Postgres with three-tier access enforced at the database layer.
Python + OpenCV in async queues for image processing.
Audit trails for every record mutation.
Results
~200,000 records under management with strict access controls.
Async image and document pipelines running reliably.
Full audit trail — every change attributable to a user.
