This project stems from the vision of using advanced technologies to create a safe and protected community from extortionists, fraud, and unwanted telemarketing.

Following the initial specifications, we developed a set of applications for iOS and Android, leveraging the native functions of both systems. We created a robust directory with a blacklist and a whitelist for calls, allowing users to decide with whom they wish to communicate.

Additionally, we developed an administrative platform that enables managers to control numbers reported for manual review and maintain a detailed record of user growth and various metrics. All of this is interconnected through a central API, which manages communication between the applications, stores and retrieves data, and notifies users when necessary.

• API: We used Node.js, Sequelize, and Express to build a robust and efficient API that manages communication between the applications, handles data storage and retrieval, and sends notifications to users when necessary.

• BackOffice: We developed an administrative platform using Next.js and Redux, allowing administrators to control reported numbers, manually review incidents, and monitor user growth and metrics.

• iOS App: We implemented the iOS application using React Native and Swift, integrating native modules to ensure optimal performance and a smooth user experience.

• Android App: For the Android application, we used React Native and Java, ensuring the integration of native modules and efficient performance on Android devices.
