Raspou Achou Ganhou — Will Bank.

Collaborated with Bunch Agency on Will Bank's "Raspou Achou Ganhou" campaign. Customers scratch a virtual card and can win up to R$1,000. I built the full platform.

The frontend is a Next.js PWA with Tailwind and Framer Motion. Register with your CPF, scratch your card, done. Added Google Analytics to track the whole funnel.

The backend runs on AWS. Lambda with Middy, SQS for queuing, DynamoDB, S3, and Postgres with Prisma. Handles validation, prize logic, anti-fraud, and sends emails via SES.

On top of that I built some tooling: CSV processing for winner lists, Instagram integration for the social side of the campaign, and a multi-threaded bot to manage entries at scale.
