Experienced data professional, with broad experience and passion for big data. Although I started in the field of economics, through my career I had the opportunity to work as HR data analyst, game data analyst, visualisation specialist and most recently BI developer, collaborating with data engineers, business, analysts and AI department. This journey gave ma an unique view and experience on how modern data platform should look like and how make it useful to the business and stakeholders. In my free time I manage a small football club in my home town, focusing mainly on organising and financial aspects. I really believe in volunteering and sharing, especially with kids, who currently are under a lot of stress and social media influence, so making them a place where they can play sports, compete in a fair play manner and just have fun is very important to me.
