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.
Thanks!
