Uniquely: serverless royalty payouts on AWS with Terraform

A serverless backend for a clothing design business that pays its designers monthly royalties.

• A monthly EventBridge job totals each designer’s sales, applies royalty rates and VAT, and sends a batch payout through Trolley
• Designers under the payout threshold roll over to the next month
• Payment status and invoice PDFs arrive through webhooks, with an HMAC signature check before any record is updated
• AppSync GraphQL API over DynamoDB, with the whole stack defined in Terraform

Stack: AWS Lambda, AppSync, DynamoDB, S3, EventBridge, Terraform, Node.js
