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?

I built a custom-made curriculum which is flexible

In this course I have shared my 14+ years of knowledge working on SQL. I have shared how you can solve any SQL problem by following standard patterns.

In this course I have shared how you can optimise SQL queries. The course is generic however it is customised to make it more specific to Teradata and Amazon Redshift
