Learn PostgreSQL Tutorial – Full Course for Beginners in 2024|
About Course
Let me take you back to 2009:
Back then, I thought I had it all figured out. I had just finished my master’s degree and thought, “Now I’m ready to work on any data project and be the best.
But then I joined my first project and walked into a meeting where I heard so many words that I had no idea what they meant. I began to feel insecure.
The month didn’t get better. In fact, it got worse. By the time the on-boarding was over, I was sitting there with all these tools, terms, tasks, and I was really frustrated.
Fortunately, I met some great people along the way who had the willingness and talent to share their knowledge about things that just seemed weird to me. So I found help in simple words and precise examples. Finally, I began to understand.
Can you relate to my story? Maybe you are at this point now. Then I want this for you.
I would love to be one of those coaches on your journey to mastering data, SQL, and databases.
