Обо мне:

My primary programming language is C++. My primary skill is Algorithms & Data Structures. Usually in my projects I mentor more junior programmers as an architect/manager. I also know Java and C#, though not their libraries and frameworks. In addition to high-level algorithmic optimization, I optimize programs with multithreading/vectorization, including OpenMP, SIMT (CUDA) and SIMD (SSE/AVX). As to machine learning, I studied Artificial Intelligence at Amsterdam University onsite, used and extended LibSVM, and have developed an interactive probabilistic question-asking system that reaches and stays at 100% accuracy e.g. on learning the binary search algorithm.

I have been programming since 1994 on my own, with work/commercial experience since 2005. At the universities I studied Artificial Intelligence (MSc) and Applied Mathematics & Computer Science (Bachelor). Primarily I was developing software for Windows, but I have some cross-platform development experience and experience working on Linux. I am familiar with multithreaded development and software reliability/data durability tasks. I have sufficient experience with SQL (MySql, MSSQL in particular). During school times I participated in programming competitions and took highest places at national competitions and got above average results at international competitions. In my spare time I participated in TopCoder competitions, though not much recently, and open source projects. My Master Thesis was in Software Architecture and Artificial Intelligence areas: automatic inference of software architecture (high level overview, nested software decomposition) from software source code. I couldn't so far find investors to let me turn it into a commercial tool.
