    Developer

    Russia - Last active: 1 day ago - 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).

    Senior Python and Django Developer

    India - Last active: 1 month ago - Tests: 1

    I have been developing web-based B2B and B2C applications in Python for the last 6 years. I have helped and guided dozens of clients to design, develop and deploy applications for their business requirements. I'm here because I have some free time these days, and would like to work on relatively smaller projects. So if you're looking for an experienced Python developer, hit me up. Even if we don't end up working together, I love talking about web-technologies. If you are reading this, the chances are you'll be having issues which I could help with. So feel free to touch base with me. Thank you.

    Senior Software Engineer

    Russia - Last active: 9 days ago - Tests: 3 - Portfolio: 2

    I have over 6 year's experience in PHP/Web development. I use PHPStorm as my primary IDE. Source-code is always stored in Git. Git is my favorite distributed revision control system. I also prefer do rebase on my branches and cherry-pick in emergency situations. For debugging PHP applications I use Xdebug and strace in very complicated cases. I'm an advanced Linux user, I usually write small bash scripts to make my life easier. I can setup working environment from scratch on server, but it's better to do it via provisioning system like Ansible.
