In the first half of 2023, my friends and I developed a data management platform for the Mexican company Kueski. This company specializes in offering small but long-term payments to individuals. In Mexico, we have something called ARCO rights, which stands for Access, Rectification, Cancellation, and Opposition. These rights allow individuals to request information held by companies about them.

They can ask for a change or update of their data for any reason. Opposition allows them to object to the use of their data while still keeping it stored, and cancellation requires the company to delete all stored data about the users. To achieve this, we created a Web App using React and MaterialUI. We used Vercel for hosting the website and planetScale for the SQL database. The app displayed all the users, allowing them to exercise any of their ARCO rights if requested. Additionally, all actions were recorded in a history log for any inconvenience or confusion.
