Have solid data extraction, cleaning and exploratory data analysis skills along with model building in machine learning algorithms for structured (databases) or unstructured (text) data. Can also perform graph analysis for all your needs depending on your project. The starting point of every project is to discuss the needs of the clients and set up an efficient data extraction - cleaning and transforming pipeline which will then be passed to any machine learning model. Can deliver all the above in an API for example in Azure ML or BigML platform so that the whole process can be streamlined and reused according to your business needs.

Python developer

Russia - Last active: 28 days ago - Tests: 3

Hello, my name is Andrey Druzhaev. I'm a PhD-student of National Research Nuclear University “MEPhI”. My work is focused on Software Development. During my study and scientific work I got a broad expirience with Python 2 and 3. Such library as numpy, scipy, matplotlib are well-known for me. Also I have experience in web-programming both frontend (html, css, js, jQuery, Ajax) and backend, but I prefer backend. For web backend development I usually use Pyramid framework with different databases (MongoDb, ZODB, SQLite under SQLAlchemy). I can work both under Windows and under Unix, can help you with Latex. I like to communicate with client, always try to meet his/her needs. I have experience in team work, know SVN and Git.
