Apple Push Notification Server for Erlang

Role in this project:

Back-end Developer

Contributions:7 releases, 1 review, 57 commits in 4 years 3 months

Contributions summary:Felipe primarily focused on developing the core application logic and structure for an Erlang-based APNs (Apple Push Notification services) provider. They implemented the application and supervisor behaviors, along with the initial connection setup using the `gun` library, which handles the HTTP/2 communication with the APNs servers. Their contributions also included establishing the application's structure and integrating external libraries like `jsx` for JSON handling and `wpool`. Further work involved adding functionality for closing the connection and implementing the backoff strategy.
