BankOS is a production-grade, enterprise-scale banking platform reference implementation. Designed to mirror the internal engineering capabilities of a Fortune 100 financial institution, it serves as the definitive architecture repository and implementation platform.
BankOS is built on a distributed, event-driven microservice architecture with zero-trust security and a GitOps-managed cloud fabric.

The definitive source of truth is the Enterprise Architecture Playbook.
All architecture documents (00-80) are located in docs/blueprints/.
Our goal is one-command onboarding. Ensure you have Docker Desktop installed.
# Initialize the full enterprise development environment
task setup
# Or via Make
make setupThis command bootstraps PostgreSQL, Kafka, Redis, MinIO, Jaeger, Prometheus, Grafana, Keycloak, and LocalStack.
- Phase 1: Enterprise Architecture Standards ✅
