Mazen Touati is a Staff Backend Engineer based in Amsterdam with a decade of hands-on experience building and migrating scalable web platforms, currently driving backend architecture and reliability at Studocu. He combines full-stack fluency and a designer’s eye—rooted in a Media Engineering master’s—with a pragmatic focus on simplicity, performance, and clear technical documentation. At Studocu he led API migrations, query optimizations, observability stacks, and helped bridge Next.js frontend migrations with existing systems while mentoring and hiring backend talent. An active open-source contributor, he improved PHP validation tooling by adding nuanced rules like NotEmoji and IBAN validation along with tests and integrations. Comfortable across Laravel, PHP, Node/Next.js ecosystems and modern monitoring tools, he’s known for turning complex system-level problems into concise, maintainable solutions. Outside work he favors calm, minimal designs—an approach that shows up in both his code and his visual work.
