AI Meets Serverless: Automating Receipt Intelligence with AWS Lambda & Textract
summary
Uploads to S3 trigger an AWS Lambda + Textract pipeline that calls the analyze-expense API, extracts vendor, date, total and line items, writes records to DynamoDB and sends notifications via SES — all wired with IAM roles, bucket policies and environment variables from a GitHub repo. Demo shows successful extractions and emails with CloudWatch logs confirming analyze-expense calls and stored entries. Handles PDFs and images but messy input and async retries require explicit error handling.
