REST and event-driven APIs, integrations, and backend services designed to last.

- Event-driven workflows + replayable event log
- Third-party integrations (Stripe, Resend, Twilio, S3)
- Background jobs with BullMQ or similar
- Authentication, RBAC, rate limiting, audit logs
- Logging, metrics, and structured error handling
Tools & stack
Deliverables
