    Backend developer

    Russia - Last active: 6 days ago - Tests: 2

    My preferred languages are Ruby and Perl, although I write PHP code quite often too. I've had a full-time job as a backend developer for the past 5 years. I'm familiar with a pretty wide spectrum of technologies in backend technology stack: relational databases (MySQL, PostgreSQL), NoSQL (MongoDB, Redis), message queues (RabbitMQ). I'm comfortable with Linux and can do server setup and some common sysadmin tasks. Currently I'm mostly looking for part-time contracts.
