Full Stack Engineer

I build multi-tenant Spring Boot systems that hold up in production: an enterprise blockchain document platform serving multiple organizations at IR4LAB Africa, and Raaqib, a stock management SaaS I architected end to end.

Multi-Tenant Stock Management SaaS

A multi-tenant SaaS that lets Moroccan clothing retailers manage stock, pricing, and team activity across locations, giving owners full visibility and price control even when they're not in the store.

Technical details

Raaqib is a multi-tenant SaaS for small and medium clothing stores. It solves a real operational problem: when an owner steps away, they lose visibility into what's selling, at what price, and by whom. Raaqib gives owners a product catalog with variants, multi-location stock tracking, supplier management, fast in-store sales recording, and a price-compliance signal that flags every sale against set minimum and standard prices. Owners delegate scoped actions to employees through a granular role-and-permission system, and view sales statistics over time. Built as a true multi-tenant platform where each store is an isolated tenant on shared infrastructure.

  • Multi-tenant architecture with ORM-level tenant isolation (no cross-tenant data access)
  • Backend designed and built from scratch with strict layering and DTO boundaries
  • Authentication with JWT access tokens + rotating, revocable refresh tokens; fresh DB-backed authorization
  • Role-based access control with granular per-employee permissions
  • Atomic, idempotent sales with optimistic-locking concurrency control on stock
  • Price-compliance engine comparing actual sold price to min/standard price
  • Flyway versioned migrations, RFC-7807 error handling, pagination, and N+1 elimination
  • Full integration test suite on real Postgres via Testcontainers, plus OpenAPI contract and CI
