Raouf Bouzerara

Backend Software Engineer | NestJS · TypeScript · Distributed Systems

I build production-grade backend systems with TypeScript and NestJS — focused on resilient architecture, clean domain modeling, and reliability under failure.

Currently open to remote backend roles (full-time or contract).

🛒 Featured Project

E-commerce Store API — Enterprise-style modular monolith built with DDD and Hexagonal Architecture.

  • DDD + Hexagonal Architecture with strict ACL gateway boundaries between bounded contexts
  • SAGA orchestration with automatic compensation on failure (refund + stock release)
  • Hybrid checkout supporting both online payment capture and Cash-on-Delivery flows
  • Redis-backed idempotency, RedisJSON cart storage, and RedisSearch product search
  • RS256/JWKS auth with refresh-token rotation and end-to-end correlation IDs
  • Observability stack with Winston structured logs, Prometheus metrics, OpenTelemetry distributed tracing, and Grafana (Loki/Tempo)
  • Containerized pipeline with multi-stage Docker, CI automation, and structured test infrastructure
