About Us

Who We Are

Dattafolio is a team of people with years of experience in databases, analytics, and reporting. We've seen how beginners often get lost in terms, conditions, and tangled queries, so we decided: it’s time to build courses that explain clearly and directly. All of us work with real-life tasks where precision, structure, and clarity truly matter. That hands-on experience is embedded in every line of our materials.


How It All Started

It began with a simple query no one could understand. We kept facing situations where technical resources only made learning harder. Dattafolio grew out of the desire to create something clear, simple, and structured. We wanted to show that SQL isn’t a mysterious language — it’s a language of logic and clarity. Our courses were built gradually, tested thoroughly, and refined to make sure every sentence matters.


Our Philosophy

We don’t promise instant results. Instead, we offer practical solutions, well-structured topics, and examples grounded in real work. Our goal is to help each person opening the material understand what's happening and act independently. We avoid clutter, overload, and empty words. There’s no random content in Dattafolio — only logic, structure, and clarity.


What We Create

We create courses for those who want to confidently extract data from tables, write precise queries, and build reports that don’t need to be rewritten ten times. Our materials are not tied to specific tools or platforms — we teach SQL thinking. These are courses that help you see the meaning behind code lines, understand query structure, and work independently.


What’s Next

Dattafolio is more than just courses. It’s a constant process of analysis, improvement, and updates. We monitor what users really need, update topics, and add new blocks to keep the quality strong. And most importantly — we’re always here. If you have questions, reach out. We’re here to help.
