Evgenii in a few words
Hi there!
My name is Evgenii, currently living in Amsterdam. I'm a DataScientist with 8 years of experience, which includes not only fitting models, or talking to managers, but also providing fine production python/scala code and documentation. I'm proficient in Reporting Analyse, Cloud Services, Machine Learning Engineering and a variety of other things. And this is what I appreciate in programming - huge amount of new different things everywhere and uncountable possibilities of doing things.

    DIGITAL & IT
    August 2019 - March 2020 (7 months)
    Saint Petersburg City, SP, Russia
    Develop 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.
