The Portal Green app, developed for the company Greenet, is a tool aimed at technicians and salespeople who work with customer registration in rural areas without internet. Its main features include:

Offline Customer Registration: Sellers can record customer data, capture geographic location and attach photos even without an internet connection.
Data Synchronization: When the internet is available, data is sent to a Node.js API, allowing technicians to view customer information and locations.
Online and Offline Maps: The app offers map visualization, including the location of registered customers, with support for offline use.
Technologies Used: Developed with React Native and Expo for the app, and Next.js for the web control panel.
