    Senior Developer, PM

    Russia - Last active: 1 day ago - Tests: 5 - Portfolio: 2

    I have strong background in UNIX/Linux software development, Master's Degree in Computer Science. I worked on Enterprise high-load distributed hosting automation systems as a Team Leader (3.5 years in SWsoft, Inc., now called Parallels). For the last 6 years I'm running my own small software development business in Russia with primary focus on Python/Django apps. Not pure Web but often involving integration with hardware (Proximity Cards, Sensor Screens) or external systems like Payment Processing, SMS Gateways, GABRIEL (Airline Reservation System), etc. I can take an idea and turn it into a working business, through all the intermediate stages. Also I have experience of investing my own funds in my projects, so I feel the difference between "perfect code" in a month and "good enough" code that increases the revenue right now. Nevertheless, my code is very good: no copy-paste, always written with performance, flexibility and security in mind, etc. On oDesk I'm looking for (and actually find :) interesting projects with a sight on long-term fruitful cooperation. I'm also open to smaller activities (e.g., consulting) where my knowledge can be helpful.

    I'm a software engineer, tester, DevOps, Linux/Windows/Mac administrator, Cloud Security & Provisioning expert. As a developer, my ability to write code in multiple languages (Java, Scala, python, C++, C#) allowed me to be assigned to critical core components of internal software platform for my current company. As DevOps Engineer I build the entire deployment and cloud provisioning story, which requires comprehensive and deep knowledge of an entire software platform with all the modules and components that needs to be packaged, the open source components (Hadoop, Spark, Mesos, Tachyon, Cassandra, Zookeeper, Rabbit, nginx, PostgreSql etc) as well as the company internal components built on top of them.
