Roman Zydyk

I am data and IT enthusiast who particularly enjoy working with data - getting them, transforming, visualizing and doing some analytics. So far I have been working more on the Business intelligence side (reporting), however I am aiming to dive more into Data science field. Coding which is very often also part of the data wrangling process is another thing I love to do - especially using Python. Because data analytics process could be challenging sometimes I like to automate as much as possible and for that purpose I used mainly Alteryx, Python, VBA and Google Apps Script. As a side projects I also created a few websites using Wordpress, Javascript, CSS and worked with basic SEO. Freelancing as an Excel/VBA developer and sometimes also lecturing basics of Tableau, PowerBI or Alteryx. Except IT I am into racket sports - especially table tennis, tennis and badminton and financial markets.
