Duplicate dispatch logs
Technical Scope
Logistics and fleet operations suffer from friction when field drivers transfer physical paperwork to back-office billing systems.
Architecture Highlights
- OCR Ingestion Pipeline: Built an ingestion bridge that receives photos of shipping documents, runs character recognition, extracts key-value tokens, and stages records for review.
- Relational Integrity: Implemented schema validation via TypeORM and MySQL transactions to ensure that financial and dispatch logs remain tamper-proof and auditable.
