Hello

Why SQL Habit?

About 10 years ago I joined my first company as a Software Engineer specialized in Ruby. Surprisingly, the first lines of code I wrote there were … in SQL . I was very curious how many users did we have, who are they and what did they do on the website, how fast are we growing as a business (the company was one of the biggest Groupon clones in ).

It’s fascinating how in just a few key strokes one can get the answer to such questions. I was hooked!

With time, I participated in many projects: competitor monitoring, content analytics (long before Medium had it), recommendation engine, business reporting etc. Data was always at the core of each project, being a compass for business and product teams.

Soon after I started my own company. It was a language learning platform which we built with a couple of friends. In just a couple of months we grew it to 40,000 users: we were running marketing campaigns, publishing blog posts, quickly shipping new features. Mega agile

I was running the company with my own money and quickly I started asking myself questions like:

• When are we going to be profitable?
• honestly it was When I won't be able to pay for my apartment?
• Shall I keep this marketing campaign or not?
• Did users like our latest feature?
• Did it move the needle in terms of purchase rate?

and many many more. One of the biggest takeaways from this experience was: all the answers are in data. You just need to ask the right question and write SQL query .

Data is #2 key to success. #1 is love and empathy for your users.

In 2015, I sold my company, moved to Berlin and joined Blinkist as an Engineer in the Growth Team. We’ve experienced 10X growth and I’m convinced that data is #2 key to success (#1 is and empathy for your users of course).

This is where the inspiration for SQL Habit came from. I’m so glad to share this knowledge with the world! SQL Habit course is a reflection on 10 years of experience working with data. Go and start your journey with SQL Habit
