Emma on Data - Invidious

Emma on Data

Emma on Data: data & AI, explained on a whiteboard. One idea per video, hand-drawn, about ten minutes.

Databricks, Snowflake, Fabric, Spark, SQL, the AI tools showing up in every data job, and the careers behind them. No talking head, no slides: a marker, a whiteboard, and one honest argument you can act on today.

Emma is the voice. The scripts come from a data engineer who builds this stuff for a living. Every video ends with one small thing to build.

Practice exams for the Databricks certifications live at testlogichub.com.

New video every week.
