I provide services such as data collection, data preprocessing, data analysis, building machine learning and deep learning models, and delivering results that can help derive insights for businesses from the data they have.
I have proven to be a data scientist who is enthusiastic about taking on new challenges
Predicted the top 20% of users that are prone to churn (it saved money to target only the high-risk consumers)
Created an automated data extraction solution that can be scaled to different markets regardless of their local data architecture for customer segmentation (it saved months for project scaling)
Provided the other types of insights answering some specific requests from markets (it saved weeks of investigation from the markets' side)
Prepared segmentation model for 10 markets, which enables further activation of 5 communication programs in the respective markets. The model outcome KPIs are used for more advanced tracking of market marketing activities
1. Interesting project/company where I can share my knowledge and improve my skills as a Data Scientist
2. To earn money is quite important. But for me is also important to deliver a high-quality service. Therefore, I want my work to be appreciated as it deserves
3. It's important for me to develop together with the people I work with so that we can share knowledge from different fields with each other (win-win strategy)

Last my job was quantitative blockchain analyst.
I used different mathematical methods analyzing cryptocurrency price changes on a crypto exchange to predict this change and play statistical arbitrage. I used cointegration, time series analysis, GRUNCH, Kalman filter, clusterisation and any other statistics.I was tasked as a mathematician to analyze all the mathematical methods that are now relevant for the analysis of cryptocurrencies and come up with a trading strategy that can be used in the Crypto Bot that we write to play on the stock exchange.
Before last my job was developing slot games. I take videos of any popular slot game from youtube or play this game online on a casino site or on site wellknown slot game companies like EGT, Aristocrat, and so on, and create game like this. I use MATLAB for modeling and analyzing created games, calculation & learning different game's statistics, first of all, RTP parameter. RTP of slot games must be between 96-98%.
Also , as scientist, I look through different scientific articles about game industry, to be able to create good modern games.
I have strong math skills, good education, unfinished PhD. I live in Ukraine, I stay all-time at home & work online, cos I am very afraid of war & covide. I send You my CV in russian and English. If you are interested, please contact me on viber, telegram,or whatsapp.
My english is not so good, so i better understand written text, instead phone talk.
