14 years ago, I had zero money in my pocket.
Not "low on savings." Literally zero.

My salary was ₹12,432 a month. I was a Database Administrator by day, and somewhere in between the work and the exhaustion, I had this quiet thought. What if
I could teach what I know?

So in 2014, I started training people. As a side hustle. No classroom. No brand. Just a genuine desire to share what I had learned the hard way.

I fell in love with teaching instantly. But I couldn't fully let go of the engineer in me, and honestly, I never did. That part of me is exactly why the training works.

Over the years, one batch became many. The side hustle became a wing of my own data research firm. And the numbers started telling a story I hadn't planned for.
45,000+ working professionals trained since 2014.

Last year alone, 200 people. Many of them cleared interviews. Many of them joined new companies. Some of them changed their entire career direction.

None of this started with money or a plan. It started with the belief that if someone had sat beside me and explained things clearly, I would have gotten there faster.
That's what I try to be for every person who joins my training.

A lot of students ask me the same thing.
“How do I build a good resume if I don’t have real experience yet?”

And honestly… most projects online don’t help.
Same datasets. Same dashboards. Same copy-paste work.

So I decided to create something different.
A complete SQL Marketing Analytics project with a dataset, documentation, business problems, and step-by-step SQL analysis.

Something you can actually learn from.
And confidently talk about in interviews.

A lot of my students ask me the same question.
“What’s the missing thing in my resume?”

Most of the time, it’s not another SQL certificate.
It’s a real project.

Not the random dataset downloaded from the internet.
Not copy-paste portfolio work.

A proper end-to-end SQL project.
With a business scenario, documentation, queries, and actual problem-solving.

That’s exactly why I made this workbook.
