I built this project entirely, including backend and frontend. Because I'm in Argentina, I've used MercadoPago for payment API, it was such complicated because the documentation it's not the best, but with its source code, it wasn't that complicated. This project was developed on NextJS 14, and I used a SQL database, it was Supabase. I used Figma for designing the landing and other sub-pages, and Tailwind CSS for the web-code design.
