After that I was in charge of supporting a website built with Java and the Spring framework, using both MySQL and Oracle databases, for customers worldwide. I also worked at the tech support helpdesk for that same company for over a year, troubleshooting Linux servers and workstations, networking and other data related issues. I was also in charge of administering KBOX ticketing system for over a year, from content management to database administration, to scripting solutions for its customers. I also have knowledge in scripting using different technologies, such as VBScript, Javascript, Linux shell scripting, Perl, and some Powershell, as well as VBA for Excel and HTAs.

    Senior Developer, PM

    Russia - 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.
