    Andrey Markin

    Developer

    Russia - Tests: 3

    I'm a Java developer moved from financial markets modeling and algorithmic trading to software development and integration architecture. My experience varies from data analysis to python, java and javascript web frameworks to java backend development and server configurations. Long term relationships with clients are number one priority, but this doesn't mean I'm not interested in just-do-it monthly projects. As a selfish egoist I'm primarily looking for interesting ones.))) I'm flexible with my working hours and am able to work closely with any existing coworkers you work with. Making a contact is a perfect and surprisingly the shortest way to start cooperating. Yours Andrey).
