Since 2014 I have been working abroad, but currently, for past 4 years, I based in France. I used to work a lot on different projects as a research scientist in different scientific institutions (mainly related to the statistical analysis in particle physics domain and in numerical and statistical modelling for the atmosphere physics). I obtained maseter in Nuclear physics in Ukraine and Master of Energy in France. Currently I am working as a Data Scientist/Analyst in a financial consulting start-up.

At the current palce the managment and team work itself just does not exist. The CEO is giving a project that he took from some rumors in the subway. Due to the so quick change of mind of the company there is no chance to developpe any solid skills and to achieve some reasonable results. I would like to work on more technical tasks, prefarably in NLP or image processing where I can use my mathematical skills. Risk analysis or financial problems solving are also welcome.
