job schedulers

(cron, APScheduler, Celery, or AWS Lambda scheduling). Basic understanding of

logging, error handling, and multithreading

Nice to Have:

Experience handling financial documents (POs, invoices). Familiarity with OCR accuracy improvement and confidence scoring. AWS Lambda or Docker deployment knowledge.

Engagement Details:

Part-time role (approx. 1 hour/day)
