Serrano.is

Contribute to the frontend development for the online ordering platform of Serrano, Iceland's premier fast-casual Tex-Mex chain. Engineered within a scalable monorepo architecture, I built a fast, highly responsive user interface using Next.js and Tailwind CSS. Because Serrano’s menu relies heavily on customization—allowing users to build personalized burritos and bowls ingredient by ingredient—I focused on creating an UI that manages complex ordering states flawlessly. To further drive business growth, I integrated a proprietary upsell-kit library that dynamically suggests tailored add-ons (like guacamole or premium proteins) during the checkout flow, directly increasing the platform's average order value.
