Customer service focused VoIP Engineer with 6 years career experience in help desk environments. Highly adept in systems analysis diagnostics and troubleshooting and conflict resolution. Exhibits excellent organizational and problem-solving skills. Works well in multicultural team environments. Lived and worked abroad. Developed traffic classification system: Fraud/not Fraud traffic. Were used several ways to solve this problems. First way, classification of traffic and each call from Call Detail Record in DecisionTreeClassifier and KNeighborsClassifier (Scikit-learn). Second way, feature generation technics, adding new features and XGBoost as classifier. Result model allows to provide better analysis of voice traffic, protect suppliers from blocking, minimal loss of money when a client was hacked.

Data Scientist

2 года опыта работы. В основном с классическими алгоритмами. Хотел бы найти работу, где я смогу использовать знания нейронных сетей и получить опыт работы со снимками, видео, аудио. Работал в банке строя модель на основании макроэкономических параметров, которая предсказывала выплатит ли кредит клиент или нет. После работал в автомобильной индустрии, где предсказывал включение необходимого режима вождения в машине на основании условий окружающей среды и также параметров вождения машиной человеком и также предсказывал потребление топлива на основании вождения. Последний проект это сегментация игроков онлайн-игр на основании их финансовых показателей. Использовал как классические методы, так и усовершенствовал существующие алгоритмы под задачу (Например, переписал Asocciation Rules под задачу персонализации инструмента в машине). Ищу новую работу, потому что внутренние процессы в компании не налажены должным образом и складывается ощущение, что менеджменту все равно. Знаю, что есть хорошие IT компании, где все с этим отлично и налажено стимуляция сотрудников к росту, чего в текущей компании нет.

Переписал алгоритм и дополнил его на основании своей креативности и под задачу. И также сделал deployment своей модели на веб-ресурсе с помощью flask (То есть сделал работу full-stack developer + data scientist)

Проекты, где я буду использовать машинное обучение и получу опыт работы с нейронными сетями, в частности с CNN, LSTM
