Meet Your Team: Rewarded Solutions

Rewarded Solutions is building a unique software solution for app and game developers that puts users’ needs first. Instead of traditional monetization mechanisms, we're building an engaging ad experience in which users can play and earn rewards for various new mobile games in our product - Playtime. To predict which mobile game will best suit a user, the team has introduced ML algorithms.

To build this rewarded experience, adjoe’s backend reliably handles more than 200 million users – remaining stable despite impressive growth in the user base. And imagine this: adjoe’s Golang event consumer applications assign rewards equivalent to 700 months’ of time spent in Playtime every day to its users. 

The software depends on two main components.

1) adjoe’s Android mobile SDK – written in a combination of Java and Kotlin – which can be bundled by developers in their apps. 

2) The team’s highly scalable Golang backend, which is hosted on AWS and is otherwise responsible for developing a modern React (TypeScript) dashboard that provides adjoe’s clients and Business team colleagues with fast-loading insights.
