Ochloi
Ochloi is a social media app running on iOS, Android and Web that we created for an British client. Users can create public or private crowds where friends and people of similar interests can hang out, chat and post pictures. Events can be created with invitations and event specific chat streams and media.
Sadly Ochloi is no longer in operation.
Technical
Ochloi is a hybrid app written with web technologies (Javascript, HTML, SCSS) using Cordova as the native layer. The server side has scalable Java Servlets running on AWS EC2 with MySQL database on AWS RDS. Messaging between clients and servers used the CometD project implementation of WebSockets. User asset storage used AWS S3. Server side processing pipeline used the Apache Camel project.
