Hi, I'm Souheil Sbayou, a full-stack engineer with 7+ years of experience. I started with a strong frontend foundation and naturally expanded into backend systems, delivering across logistics, SaaS, and AI. I enjoy solving ambiguous problems and building robust UI with React and Next.js, server-first architectures, and polymorphic UI components.\n\nI specialize in end-to-end system design: from complex state management and client data delivery optimization to durable backend workflows, serverless and edge deployments, and AI/agents integration. I value observable systems, scalable monorepos, and data-driven decision making, and I thrive in teams that are still figuring out the problem itself.
