GeoLocationRange: geolocation distance and image OCR pipeline

Build a reliable media+OCR pipeline where input quality and DB format differ strongly between sources.

Responsibilities

• Support worker-based OCR stage with Python tooling.
• Validate coordinate data and distance calculations with configurable precision thresholds.
• Store media and OCR artifacts in durable object storage layout.
• Keep long jobs observable and recoverable via queues and retries.

Role: backend engineer — data pipeline and deployment-hardening support.

Introduced bounded queue workers for OCR ingestion, centralized config of thresholds, object storage routing, and scheduled housekeeping tasks. Added observability around failures and retry windows for long-running jobs.
