What the team does

Wildlife is one of the largest gaming companies in the world. Besides building amazing games, part of the reason it has been super successful has been its ability to acquire new users more efficiently than other companies. To keep strengthening its user acquisition capabilities and competitive advantages, Wildlife has built its proprietary real-time ad buying technology platform (DSP – Demand Side Platform), which competes in millions of auctions per second against Facebook, Google, and other marketing channels across all mobile in-app ads inventory. Its main goal is to leverage Wildlife's data to buy advertising space in other mobile apps so Wildlife can promote its games more effectively than other gaming companies. 

The DSP receives one million requests per second, all of which require response times under 100ms. To handle the low-latency and high-throughput requirements, it is built in Golang over a distributed architecture, with all its infrastructure hosted on AWS. To handle distributed training and validation techniques on large models (+100 MM params) fit on PBs of data, the team leverages TensorFlow in combination with Spark, through Databricks and Petastorm.
