TuniWork is a premium freelance marketplace tailored for the Tunisian market, connecting skilled professionals with clients. I engineered this high-performance platform using Next.js App Router and Tailwind CSS. Key technical achievements include a custom zero-dependency i18n architecture providing instantaneous translations across French, English, and Arabic, complete with dynamic RTL layout support. Additionally, I implemented dynamic native currency conversion, elite multi-language SEO strategies, and a highly polished responsive UI to ensure a seamless, modern user experience.
