Petr B.

Senior Developer, Consultant

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.
