  • Data Scientist with strong math background and 10 years of experience using predictive modeling, data processing, and machine learning algorithms to solve challenging business problems. I have design & coding skills, as well as an ability to build data pipelines for training models and serving them. I am constantly learning and never say "I can't.
  • I apply different kind of data manipulations, statistics and machine learning techniques to extract knowledge from market data and generate ideas for algorithmic trading. Ideas are transformed into models which I prototype via Python, R and then - implementation on c
  • ++ new strategies for trading. Also, I create different tools and dashboards for data visualization, manipulation, analysis, analytical tools, parsers, scrapers, different "working horses", which works on daily basis with different data sources. Developing, integration and maintaince of new software functionality. Implementation of web interface for different tools, visualization via Shiny or Jupyter dashboards.  Developing simulators, backtest systems.
