The challenge
Built a dual-engine OCR system combining Mistral 7B and Google Cloud Vision to extract structured data from printed documents, handwritten text, and complex table layouts.
What we built
A production system designed specifically for this problem — not a template, not a configuration of existing tools. Every architectural decision was made to maximise accuracy, minimise latency, and integrate cleanly with existing workflows.
