I DON'T HAVE TIME FOR ODESK ANYMORE The 2012 year with exception of a couple of months I dedicated to development of my own SAS: http://msgnotes.alehro00.com. Which still requires a decent amount of work in web design and marketing areas. Although the project isn't commercially successful it allowed me to climb the stack of JEE6 technologies. The web server is running under Glassfish on AWS EC2 instance. The client app is Thunderbird add-on. It has commercial and free versions. Starting from 2011 I'm developing mostly with such a tool-set: Eclipse, Java, JavaScript. Over 2006-2010 years, I had participated in development of well known trading and traiding automation system (Multicharts). Also I took part in development of small business applications. The skills I was using extensively those years: development in C++ for Windows, COM servers and clients, multithreading, OOP, STL, boost, .NET. I know that this preamble looks not quite typical. It has simple explanation. I'm in process of transition from C++/C# desktop development to Java based Web development. So, I'm quite professional in .NET but I don't consider .NET as area of my interest any more. Also, since I'm kind of beginner in Java Web development, I'm halving my hourly pay rate.
