PayperChain
Refactored the payment dashboard for a blockchain-based pay-per-use platform.
- blockchain
- openapi
- kubernetes
- docker

PayperChain lets machine builders bill their customers per use, with the payment and invoicing logic running on a Corda distributed ledger. The dashboard is where operators see usage, payments and invoices in real time.
The dashboard got a new interface and data layer, and was connected to the middleware that keeps it in sync with the ledger's payment and invoicing workflows.
What I did
- 01
Full refactor of the React dashboard and its state management
- 02
Real-time sync with Corda flows through the middleware API
- 03
Keycloak-based authentication and roles
- 04
API mocking, so the dashboard can be tested without the ledger
