Description
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.What can you expect to learn in this course?We will start at zero, 0, null. Promised!Use lots of examples and small steps to build your skills.Sprinkle in a lot of exercises and repetition.If you ever get stuck, don’t hesitate to send me a message.We can walk this path together.I really look forward to seeing you in this course!
