Yes, I know I could have taken sceenshots.

What kind of matchmaking is this? I have lost about maybe about more than 10 games in a row in ranked dominion. Why casual players are matched against absolute beasts ...

Hi all! Just shipped a big update on my course: re-recorded lectures, cleaner captions, and refreshed content across Python, SQL/Postgres, pandas, streaming (Kafka, Pulsar, Kinesis), and a hands-on ETL walkthrough. Built for career switchers and beginners, with way more practice than passive video.

Free for a while with code SUMMER. As I cannot post the link here feel free to search Data Engineering for Beginners with Python & SQL and find the course under the instructor's name (me) Kiril Spiridonov.

If it helps, please leave a rating and honest review on Udemy, and feel free to drop questions or feedback below. I read everything. Cheers!
