I am working in the Russian branch of an international company in Novosibirsk (Russia) as the software engineer ("Software Engineer V") and the leader of the small team.

Now I believe that my level is so high that in C++ and MS Windows the specific "technology" does not important to me. It is probably enough to say that in my last shareware project (Your Voice Reminder, year 2006) I substituted my own clocks instead of the regular Microsoft in the MS Windows taskbar and implemented my own code to record and clear the voice messages including trimming the pause at the end. So now theses clocks may say date and time with your own voice. Also when I made a (limited time) test client / server project for a company to get the job (year 2006), I made the best project (as they estimated it) though I had no previous experience in the client /server programming.

The most large software that I made myself from the scratch had more than 60,000 lines of code and more than 300 C++ classes.

During seven years I was the manager of the successful software project in my own small software company (less than 5 people) where I was also the executive manger. The corresponding software was purchased by many Russian phone companies.

I know English and a little French.

I worked in USA (H1b visa only) and have the valid USA social security number.

Before 1993 I was a scientist and have Ph.D. in physics and mathematics.

After 1993 when the salary of the scientists in Russia dropped below the survival level (less than $100 /months) I became the Software Engineer.

Worked across the whole software -- in virtually all aspects of software design and implementation. I also worked with cross functional teams and as the project manager.

Besides C++ I also developed in Java.
