ConstraintThe product problem
An AWS Textract-powered extraction service with OCR processing, spell correction, lexical similarity, and an Express API. The engineering challenge is to turn that scope into a legible system with explicit inputs, dependable workflow boundaries, and an outcome that can be inspected and maintained.
SystemThe architecture decision
The reviewed implementation routes document / query through ingestion, extraction & retrieval, crosses document, storage & model services where required, and produces extracted / grounded result.
OutcomeThe operating result
AWS Textract Service is included as documented engineering work. Its source structure, technology stack, and functional flow are presented here even though no verified public deployment is currently available.
