A Telegram-based AI system that converts invoice images and PDFs into validated financial records.

Challenges

Invoices varied in format, layout, and image quality, making accurate extraction difficult. I built a multi-stage pipeline that handles different file types, normalizes AI outputs, validates financial fields, and rejects previously processed invoices.

Results & Impact

Replaced manual invoice entry with an automated document-to-data process. Each invoice is analyzed, validated, checked for duplication, archived, and converted into structured accounting data—improving speed, accuracy, and financial record reliability.
