    About Me

    United States - Tests: 2

    I am a Permanent Resident here and I have lived 25 years of my life in Iran before I immigrate to United States. I graduated with a B.A in English Literature from Shiraz University; I have worked part time and full time as an English teacher, translator and assistant in different schools and agencies. I exhibit many qualities that constitute a cross cultural educator. I spend a considerable amount of my time researching different subjects for my translations and classes, on a daily basis. I currently use a combination of search engines, libraries and sometimes eBooks for my purpose. I also teach English to a variety of learners, coming from different ages and social class; establishing a successful connection with the students while using modern methods of teaching to ensure a live and effective stream of learning. My former Students’ skills in reading, writing, speaking and listening were greatly improved at the end of each semester. I also was an administrative assistant in International Organization of Migration, easing communication between the IOM members and Afghan refugees with oral translations and guidance. My skills in English and oral presentations resulted in a very smooth communication between the refugees and the staff. These positions afforded me the opportunity to have direct interactions with diverse populations of people and therefore helped to foster my skills and knowledge as an educator and an organizer.

    Petr B.

    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.
