One thing I’ve noticed from interacting with aspiring data professionals is that not everyone needs another course.
Some already know SQL, Python, Power BI, and even modern data engineering tools.
Yet, when it comes to interviews, they struggle to communicate what they know.
And I think there’s an important distinction here.
Knowing how to use a tool is different from knowing how to demonstrate its business value.
You can build a data pipeline. But can you explain the business problem it solves?
You can create a dashboard. But can you explain the decisions it enables?
These are skills you develop through exposure, deliberate practice, and constructive feedback.
And that’s where mentorship becomes valuable.
Sometimes, what you need isn’t another tutorial. You need someone with industry experience to challenge your thinking, review your work, and help you communicate your value with confidence.
That’s the gap I’m helping aspiring and growing data professionals bridge.

Day 3 of my Data Engineering journey ⬆️💪🏿
GROUP BY lets you summarize rows with identical values in a column into groups.
It is mostly used with aggregate functions: SUM(), AVG(), COUNT(), MIN(), and MAX().

Check out your life goal again before you jump on a new thing.
New week, new thing does not mean this:👇

The HAVING clause lets you filter the summarized groups based on a certain condition.
While WHERE filters rows before grouping, HAVING filters groups after grouping.
