About Me


I am an industry expert in BI ETL processes, data transformation, data visualisation, project management and automation projects.

My Profile

Who am I?

I have experience in data visualisation, digital marketing, data analytics and  web development. I have worked as a senior account manager for the biggest global media agencies. My main mission was to connect the data (a variety of sources like Google Analytics, Facebook, Youtube etc) in business intelligence tools and build the reporting dashboards (HTML, CSS, JS, JSON queries). I got involved in projects related to famous brands (either for clients or POCs) like Red Bull, Activision, Disney, Burberry, GSK and many others. I have offered and presented a number of solutions/tools (professional services). I have managed to automate the daily processes of reporting dashboard building and data baking. I am always ready for new challenges.



Experienced in data management and visualisation. Always keen on challenging tasks.
