- Game of WhalesData Scientist / Machine Learning EngineerDIGITAL & ITAugust 2019 - March 2020 (7 months)Saint Petersburg City, SP, RussiaDevelop and tuning of ML models, based on neural nets.The company itself - b2b for mobile game developers, provided variety of services to keep track on efficiency of the game. My part was to create a model, suggesting some possible in-game pop-ups to encourage in-game purchases. As it's hard to maintain every model separately, and each game has its own unique set of actions, purchases, currencies, statuses and overall flow of gaming experience, I had to create sort of Fabric for NN models, create a proper validation and testing over multiple datasets and maintaince/reporting dashboards about it.
