    Looking for a position as a sr. developer / project manager.I have been developing software for web applications for over 10 years, I am well versed in PHP, Perl, HTML/CSS, JavaScript and Ajax. Also i am an expert in related areas as UI development, so I do not require constant supervision since I'm able to improvise in case the specs are incomplete and if I have permission to do so. I am working very fast, hiring me you get not only top quality, but reasonable price too.I have some ready-to-use functions\classes which comes with me from project to project, which allow me make custom code to easy handle high-load sites and don't require wasting time for routine tasks same time. I am online very often, including holidays, you can be sure you will be able to reach me within one day no matter what your timezone is.

    Senior Developer, PM

    Russia - Last active: 3 days 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.
