Более 5 лет применяю анализ данных как основной метод решения бизнес-задач. Проекты (от новых к старым): 1. Картирование плотности населения Киева, чтобы найти подходящие локации для открытия новых магазинов Watsons. Использован R, Selenium, Shiny, Yandex Geocoding API, MS SQL. Источки данных: сайт ГИОЦ, данные о геолокации домов, остановок транспорта, магазинов с Google Maps и Yandex Maps, результаты подсчета пешеходного трафика, результаты счетчиков трафика магазинов Watsons, статистика продаж магазинов. 2. Кластеризация покупателей Watsons, чтобы сформулировать отдельные коммуникационные и промо стратегии для каждой из групп. Использован R, MS SQL, K-mean cluster analysis. Источники данных: персонализированная статистика продаж по карточкам лояльности Watsons из Siebel CRM, доступность стока по магазинам, календарь промо активностей, календарь рассылок. 3. Поиск факторов влияющих на продажи магазина Watsons, построение предиктивной модели для инвестицинной оценки открытия новых магазинов. Использован R, PCA analysis, Google geocoding API, MS SQL, регрессионая модель с помощью нейросети на Keras + Tensorflow. Источники данных: еженедельная статистика продаж всех магазинов Watsons за последние 5 лет, информация о наличии стока в магазинах, более 100 факторов в динамике описывающих каждый магазин и его окружение, экономическая статистика Украины. 4. Оценка минимально приемлемой ликвидности для Beiersdorf UA, чтобы разместить излишние средства на депозит. Использован R, MySQL, descriptive statistics. Источники данных: выгрузка банковских выписок по счетам компании за последние 5 лет. 5. Оценка уровня baseline продаж+трендов по товарным группам Beiersdorf UA, для правильного промо планирования. Использован R, MsSQL, time series analysis. Источники данных: ежедневная статистика продаж дистрибьюторов компании за последние 2 года, календарь промо активностей, отчеты о промо расходах.

Python Developer

I've recently graduated with master's degree in Computer Science. I don't have commercial experience yet. I've been usually carrying out the following tasks in the projects I've been involved in during my studying: + data pre-processing including data cleaning, noise and missings removal, anomaly detection. + searching for relationships between variables. + dimensionality reduction for datasets with large number of variables, using the following techniques: PCA, MDS, t-SNE. + data clustering using the following algorithms: k-Means, hierarchical clustering. + building classification models mostly based on MLPs and SVM, but the following algorithms were occasionally used: linear/logistic regression, stochastic gradient descent, naive Bayes. + models evaluation using different test scores. + data visualization using various techniques. Besides what was mentioned earlier, I have experience in the following topics: + working with 'requests' library for data scraping, 'regex' for parsing textual data, etc. + working with SQL databases, performing not very complex SQL queries. + building basic multithreading and multiprocessing applications. I'd like to continue my path as a Data Scientist. I'm really passionate about AI, computer vision, machine learning, big data, etc. Though I wouldn't mind working as a Software Engineer, as I want to improve my skills and try different aspects of the IT industry.

My background is analyzing and forecasting data of Ukrainian economics as former analyst in state government (division of macroeconomic analysis and forecasting). My responsibility was preparing different kinds of reports for management. One of my achievement there was accurate forecast for inflation in situation when we had a devaluation of UAH and sharp increase in gas tariffs in 2014. I always taking into account many different factors when making any decisions. Analyzing is a part of my life in any situation. So I would like to realize myself in data analysis in future with using different program tools. I'm ready to get position related to this field of science to bring myself closer to my goal. I have basic knowledge of Python and its libraries like NumPy, pandas, matplotlib, statsmodels. Also know SQL and Git. I know html and css, have common knowledge of JavaScript. I am a team player and good-learner always looking for self-developemnt and improving my knowledge base. I've finished already: - Data Analyst with Python career track on; - Berterlsmann Data Science Challenge Scholarship course on which was included 3 parts: descriptive statistic, Python and SQL; - frontend course from GoIT(with all homeworks on GitHub). To practice in data analysis I created projects on GitHub. Now I have forecasts of some world commodity prices by using Arima model.
