Meet Your Team: Rewarded Solutions - Mobile Integrations
The Mobile Integrations Team is part of our Rewarded Solutions Department which develops the technology behind adjoe's innovative rewarded engagement products that serve over 57 million daily mobile users.
Mobile Integrations is responsible for the native Android and iOS SDKs written in Java/Kotlin and Swift that handle much of the complex engagement flows. On top of the SDKs are widely customizable web applications built with React TypeScript; and a highly performant Golang backend hosted on AWS that processes millions of events hourly. Our system matches each game with its ideal users, delivering rewards optimized for satisfaction through data processed via AWS Athena, Kafka, Spark, S3, and MySQL.
For team members, this means having state-of-the-art resources to build engaging rewarded ad experiences that seamlessly integrate into the world’s top apps while delivering exceptional results for advertisers and monetizers in this industry-leading technology.
