About Rafael J
Hi, I'm Rafael, a Systems Engineer and data analyst. I have worked for over two years integrating and validating business data with SAP, SQL Server and Power BI, building reports and dashboards that companies use to make decisions. I hold a Microsoft Power BI certification and I am completing IBM's Data Science Professional Certificate. Outside of work I build my own projects, such as xG-Compass, an app that predicts football matches across five European leagues. I enjoy explaining technical topics in a clear and patient way, so my students feel confident working with real data.

My classes are 100% hands-on: you learn Python, SQL and Power BI by working on real business cases, not just theory. A typical lesson starts with a quick review, then we build something together, such as cleaning a messy dataset, writing SQL queries or designing a dashboard, and we finish with a small exercise for you to practice on your own. I explain every concept step by step and adapt the pace to your level. What sets me apart is that I have worked for over two years as a data analyst and build my own projects, so you learn the tools and habits used in real jobs. Lessons are for beginners, university students and professionals who want to start in data analysis or strengthen their skills.
