Challenge

Needed clear service boundaries for wallet, ledger, docs, and orchestration while supporting auditable event flow and API security.

Approach

• Structured a Node.js monorepo around deployable services and shared packages.
• Adopted Kafka-based event distribution with fallback outbox support.
• Introduced API key enforcement and allow-list CORS controls across services.

Implementation

• Wallet + ledger service surfaces with docs portal.
• PostgreSQL persistence mode and migration workflows.
• Docker-compose stack for integration and local validation.

Outcomes

• Faster internal integration testing across wallet and ledger flows.
• Improved auditability through explicit event contracts.
• Production-ready deployment baseline for regional rollout.

Technology Stack

Next Steps

• Add tenant-level observability dashboards.
• Formalize SLA metrics on orchestration and webhook delivery.
• Expand integration console for partner onboarding.
