I am Grzegorz Bączyk and I am creator of PowerBusiness. I am happy that you visited my page. I am working with data analysis since 2014. I cooperated with many organizations such as Nordea, PwC, ING. I share my experiences in working with Business Intelligence tools on blog. My career is based not only on data analysis but also running courses in different companies as both internal and external trainer. I try to work with best practices and innovative methods that facilitate our work so you can expect short and simple articles that can be immediately implemented in your daily work with Power BI, Excel, or SQL.
