I'm software developer since 1996. I started with assembler on Intel 8051 CPUs, during years I was interested in C, C++, Sybase PowerBuilder, PHP, Sybase Anywhere Database, MSSQL server and multiplatform development.

Currently I'm developing in C++ and C# (this is my favorit and I spent some time with MCPD achievement). I'm also interested in design patterns.
