Jubinmitra
What you're doing with the minibio on your user page is not really outside of usual Wikipedia procedure - whatever they say, WP:Autobiography doesn't rule out having an informative user page.
That said, writing it in the third person looks really pretentious. Or, worse, someone might think that you're trying to play a fast one on them and con them into thinking it's a genuine Wikipedia article (which would be silly, since anyone can see the heading User:Jubinmitra at top, and knows it's not an article). But that might be why you get the negative reaction.
Just say "I'm this" and "I'm that". Look up WP:Userboxes and see if there are some you want to use. Maybe try not to make it sound so much like a resume, ehm I don't know, that's your call, I've never been to India.
But remember: on Wikipedia, what looks the best is what you do. If you're serious about using your Wikipedia work to promote yourself, learn how to start an article so it sticks, how to get articles to good and featured status. Get some good work out and then you can toot your horn about it.

Wikipedia is not for writing about yourself edit
Welcome to Wikipedia, but it is not a place like Facebook or LinkedIn for people to write about themselves or post their CVs. It is a quite different sort of site, a project to build an encyclopedia, so it is selective about subjects for articles, and writing about oneself is strongly discouraged, for reasons explained at Wikipedia is not about YOU and Wikipedia:Autobiography.
Wikipedia user pages are not like those at social-networking sites. Their use is explained at WP:NOTWEBHOST:
"Wikipedians have their own user pages, but they should be used primarily to present information relevant to working on the encyclopedia. Limited biographical information is allowed, but user pages should not function as personal webpages or be repositories for large amounts of material that is irrelevant to collaborating on Wikipedia. If you are looking to make a personal webpage or blog or to post your résumé, please make use of one of the many free providers on the Internet or any hosting included with your Internet account."
You can find out more about Wikipedia at the WP:Welcome page and the WP:Introduction. JohnCD (talk) 14:00, 17 April 2016 (UTC)
