Payments
A secure multi-tenant payments API platform
- Node.js
- PostgreSQL
- Kong
- OAuth2
Challenge
A payments provider needed to expose services to partners without duplicating infrastructure per client, while keeping each tenant's data strictly isolated and every request auditable.
Solution
We built a multi-tenant API platform with per-tenant isolation, OAuth2-based access, rate limiting, and end-to-end request logging, designed so onboarding a new partner is a configuration change, not a deployment.
Technologies
Node.js services behind a Kong API gateway, PostgreSQL with row-level tenant isolation, and OAuth2 for delegated access.
Outcome
Partner onboarding dropped from weeks to days, with a full audit trail per tenant and no shared-state incidents in production.
Ongoing
The platform is maintained under a support agreement, with security reviews on each significant release.
