Open Banking System

Banks needed to expose accounts, payments, and history to third parties under PSD2 while keeping security and observability tight. They also required a developer-friendly portal for registration and ongoing support.

We built an open banking hub with secured API clusters, SCA client authentication, and a self-service developer portal for documentation and support. The stack includes API gatewaying, identity via Keycloak, and observability with ELK/Grafana to keep integrations governed and auditable.
