Meet Your Team: Advertising Solutions

The Advertising Solutions team builds technologies that connect advertisers with ideal users for their apps and games. Integrated with adjoe’s ML models, our custom APIs serve 2B requests per day at low latency.

We've developed advertising campaign management and complex analytics tools that provide actionable insights on 200 million daily users to both internal teams and external partners. Our Go-based backend feeds data to a TypeScript React frontend, supporting sophisticated analysis tools built on columnar databases like Druid for sub-millisecond query response times, complemented by MySQL, Redis, DynamoDB, and Kafka.

For developers, this means working on high-performance systems that process massive datasets while maintaining an agile development approach – implementing advanced algorithms through deep learning approaches for campaign distribution and bid optimization, building intuitive dashboards, and creating APIs that power business decisions across the entire advertising ecosystem.
