About me

Hi, I'm Volodymyr. My job consists in helping companies and researchers to analyse their datasets. I am skilled for most data-science steps: data pre-processing, data analysis, data visualization and results communication. I am a open source believer since I think with sharing solutions we can achieve a lot more as a community. Therefore I prefer to use R and Python for my daily work. On my website you can find some examples of my projects, most of them are links to a jupyter notebook or interactive visualization. Have fun in browsing through the content and thank you for visiting!
