About me

About me


 
 
I am Nitin 'Raj' Srivastava – founder/author of ETL-SQL.com. This website shall help you in understanding basics of Data Engineering with Teradata & Amazon Redshift. 
 
More focus on the SQL part as I want to share my experience as an ETL-Developer and Data Engineer. I have designed this website in such a manner that even a beginner shall understand concepts easily.

The journey started in 2009 when I posted my first Teradata blog. The intention was to provide e-space where readers can find valuable Teradata tips. Back then, there weren't many Teradata blogs. 
 
In this blog, I have tried to cover Teradata , Amazon Redshift, ETL & Data Warehouse Concepts, SQL Queries.

In the past 14 years I have given as well as taken loads of interviews on Data Engineering. So I also share interview tips and tricks on this blog.

I would like to take this opportunity to answer few FAQs:

How often do you update your website?

Whenever I find something interesting in my day to day work and I feel others may too want to learn it then I put it on blog.  Also I do revisit my old posts once I have gained more knowledge and I can add to existing posts.

How about Online Trainings?

If you are looking for any specific topic then feel free to give us a shout out with topic details and we will try to cover it in our future posts. However if you wish to cover several topics and feel training is much more beneficial than just reading a blog then you may contact us too. I am always happy to help you.
