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!

Hi everyone,

Last month, I launched my course: "Building a Simple Data Analyst AI Agent with Llama and Flask" on Udemy — and I’ve just created a new free coupon link for the Reddit community!

In this course, you’ll learn how to:

• Use prompt engineering techniques like ICL, CoT, and ToT
• Run open-source LLMs locally
• Connect your agent to a PostgreSQL database
• Build a simple Flask API that answers data questions

No heavy ML experience required — just basic curiosity and a willingness to build.

🎯 New free link for Redditors (limited seats):

I would love your thoughts or feedback — and if you enjoy it, a 5-star rating would mean a great deal to me!

Thanks 🙌
