In my recent work, I’ve designed modular ERP platforms, built microservices with event-driven messaging, and improved performance through refactoring and query optimization. I also enjoy tackling complex integration challenges (e.g., micro-frontend architectures, AI-assisted performance tuning, and multilingual/multi-tenant flows), and I’m committed to clean architecture, SOLID principles, and continuous delivery through CI/CD and testing.…I’m Youcef, a mission-driven full stack developer with 7+ years of experience building and modernizing production-grade ERP and distributed systems.
