Regression analysis / Classification / Clustering / Computer vision. Experience with methods: SVM / Bayes / Neural Networks (Convolutional networks)... Data structures / algorithms. Multithreaded (or multiprocessing) / concurrent and parallel idioms. Expirience on working with big data. Good knowledge of programming paradigms OOP / Metaprogramming (C++). Little practice in functional paradigm (Haskell). In the same way I prefer to use functional paradigm in C++ / Python C++98/11/14/constexpr17: stdlib / boost / json / opencv / cpr / hana / modern rangev3 / etc. Knowledge of modern c++ metaprogramic idioms. cmake, valgrind, gmock / gtest / bandit. In C strong experience with ffmpeg, CUDA, cuDNN, cuBLAS. Python3: pandas / numpy / scipy / matplotlib / theano / scikit-learn / tensorflow / requests / etc... R Language and Haskell for some practice. C# and Java with strong practice
