In my primary job as a data scientist, I developed stock outlier detection mechanisms; price forecasting models; behavioral prediction models for indices and regressive models for reasoning about market statuses. Similarly, I developed decision mechanisms for an automatic portfolio managing system, with integrated causality and time series analysis. As an analyst, I tested the market behavior hypothesis, organized historical backtests for models and prepared nuanced interactive reports for brokers. As an architect, I supervised the creation of internal data storing/processing service with built-in indicators, predictive analytics, and data scrapping engines. I have also significant experience with other, smaller independent projects that I have done in the data science market. And I have academic research experience.

Я помог собрать команду с которой мы смогли создать персонифицированный внутренний трэйдинговый сервис. Сервис выполнял аналитические функции, одновременно проводил запросы к БД и сервису Блумберг, предоставлял трэйдерам квоты и советы по стратегиям. Также я курировал проект по интернет трафик анализу который был оптимизирован для обработки поведенческих данных клиента в форме графов.

Я хотел бы работать в компании у которой арзитектура готова для продвинутого data scientist в которой я смог бы полностью раскрыть свой потенциал.

Я занимаюсь изучением данных, ищу в них закономерности для последующего извлечения полезных сведений. Применяю для этих целей подходы, в том числе предоставляемые средствами математической статистики. В качестве основного инструмента использую язык R, в качестве вспомогательного — Python (NumPy, Pandas, SciPy, Scikit-Learn). Участвовал в исследовательских проектах с научным уклоном. Обладаю углублёнными познаниями в области психологии. Имею опыт разработки на языках: С++, C#. Знаком с методами машинного обучения. Обучал модели для задач предсказания и классификации. Приобрёл ценные знания и навыки в качестве руководителя команд исследователей и разработчиков. Сейчас определяю как основные направления для развития: анализ данных, машинное обучение. Также буду рад случаю применить и улучшить свои навыки руководителя.
