Production-Grade Build
Northstar Platform
A service-marketplace backend built to production standards
End-to-end backend I designed and shipped: multi-role authorization, async job processing, and a fully tested API. The code is public — it is the evidence.
- JWT + RBAC across 4 roles, enforced at the guard layer
- Async work offloaded to BullMQ + Redis with idempotent workers
- 28+ tests covering auth, workflows, and edge cases
Key decision
Modular monolith over microservices — one deploy, clear boundaries, less ops overhead at this scale.
Tradeoff accepted
Horizontal scaling is container-level, not per-service. Acceptable until traffic demands service split.
