The web portal is offering free and controlled access to the following:
• Online courses made of lessons, formative assessments, and summative assessments leading to the issuance of certificates.
• Finance-related casual games: a quiz game, a prediction game, and a memory game.
• A Web3 portal for trading MOGA tokens.

Users are authenticated with an Open Campus ID, which associates them with the credentials (NFTs) published on the EDU Chain.

Users can also register different Web3 wallets (Web wallets, mobile wallets, and hardware wallets) to view and manage their MOGA assets on the EDU Chain.

This repository showcases how a modest Family Budget Tracking system can be simply built on AWS infrastructure:

• The front end is hosted on the Amazon S3 setup for website servicing.
• The business logic runs on an AWS Lambda function.
• The data persistence assumed by Amazon DynamoDB.

The project has been built with [Kiro](https://kiro.dev) in _spec_ mode.

As software architect for the Waggle project, I designed a lightweight course format (JSON on S3 with metadata in DynamoDB) to replace a costly learning database ($1 million a year). Content authors could use a web app to create courses with full interactivity (MCQs, FiB, sorting, etc.) for students, ensuring nothing was lost in translation. The solution leveraged S3 and CloudFront for lesson delivery and Lambda functions for student progression tracking. Most assessments were auto-scored using solutions documented by authors, while a dedicated pipeline handled offline scoring by teachers for textual answers such as essays. Ultimately, the operating costs of the entire publication pipeline were around USD80k/ year.
