In a way, being an director or VP involves CRUD and ETL on people instead of computer systems.

That is correct. English is not my first language.

Just curious, since you found out from my writing style what particular sentence stood out as odd to you.

Do you know any resources to assimilate to American English in verbal and written cases ?

Briefly

    near -> nearly

    well familiar - delete the 'well'

    Since last 3 years -> For the last three years.

    I work as manager -> I work as a manager *or* I am a manager *or* I have worked as a manager.

    What are things -> What are the things

Beyond that there's some minor style issues. The misuse of 'since' is common among German and Dutch speakers so that would be my guess of your native language. I don't think any if this is a blocker for a director position but get yourself a good partner / secretary.

"Well familiar" isn't too strange a construct, though removing the well does certainly improve things here.

"quite familiar" seems more natural to me. Also, the odd comma spacing immediately jumps out at me.

Certainly "quite familiar" is more common.

The big clue was missing definite articles (a, the, etc.) and lack of plurals. There is some strange grammar as well. If I had to guess I'd say your first language is probably an Asian one, like Chinese or Japanese? These mistakes are common coming from Asian languages as they do not have these constructs.

I have rewritten a corrected version of your post -- I've tried to highlight the changes. Let me know if you have any questions!

I have nearly 10 years of experience. I have worked on ETL, Data migration, and CRUD applications. I am familiar with data warehousing and BI concepts, and have worked on many projects involving both. The last 3 years I have been working with Big Data applications on the Hadoop platform, mostly writing code in Java and using abstract languages/platforms such as Pig, Spark, RedShift, and Hive. I am tired of ETL, data cleaning, and slicing and dicing projects now.

From a business standpoint I have experience with healthcare, insurance, advertising, and a little bit of finance.

I want to contribute to something big and grow professionally. I work as a manager for a mid size company in the bay area. I want to join my next company at the Director level or higher.

What are the things I should learn to grow professionally?

What are the things I should keep tabs on beyond technical knowledge for getting Director or VP roles? How do I cultivate this change?

> Since last 3 years I have been working with

This sentence gave it away for me. More natural statement would be "Over the past 3 years I have worked with ..."

Spaces before punctuation are the giveaway.
