Gestorama

Gestorama allows consultants and influencers to create and share groups with exclusive content by charging their clients through monthly subscriptions.

The app's front end provides a great user experience and follows the guidelines for material design. I designed and prototyped the application screens and implemented them using React Native.

I also implemented the serverless REST API using Google Cloud Functions to handle all the traffic and manage payments, authentication, and notifications. I implemented each endpoint to provide all the data for the front-end application while following requirements and used 3rd-party APIs to provide services. It was created with Google Cloud Services and TypeScript.
