Hi, I’m Souheil Sbayo, a front-end focused full-stack developer with 7+ years of experience building web apps, mainly SaaS products and B2B platforms. I’ve collaborated remotely with globally distributed teams, cultivating ownership, independence, and a flexible, communicative mindset. I enjoy turning complex workflows into intuitive, interactive experiences and designing scalable UI systems as part of end-to-end product development. I specialize in React and Next.js apps with a Server-First Component Architecture, efficient partial pre-rendering, and performance optimizations through caching, memoization, and revalidation strategies. I build reusable data access layers and integration SDKs for GraphQL, REST, and WebSockets, orchestrate advanced state management via state machines and atoms, and implement robust testing, observability, and CI/CD practices. I’m passionate about delivering maintainable, scalable software and collaborating across disciplines to ship high-quality products.
