Backend & System Architecture Engineer · Algiers

  • SaaS
  • Enterprise Integrations
  • Distributed Systems
  • AI-Assisted Software Development

I design and build reliable backend systems, SaaS platforms, and integrations between complex business applications. My work focuses on system architecture, API design, data modeling, authentication, multi-tenancy, asynchronous processing, observability, and long-term maintainability.

I use AI-assisted engineering to work efficiently across programming languages and technology stacks, selecting tools based on system requirements rather than being limited to one framework or language.
