Hi, I'm Barbara Callegari and for over 10 years I've been helping professionals, companies and students understand (and actually use) tools like Power BI, Excel, Python and artificial intelligence applied to data. I'm a Microsoft certified trainer and Python Associate certified, but above all I'm a person who loves making complex concepts simple. In every course, whether live or recorded, I have only one goal: to transform theory into practical skills, useful in everyday work.
