Leigh's sentence is how most natives would say what you wrote and what's more we would often add the next sentence on to that!

For instance, "I'm a 26 year old software engineer from China who loves dogs and likes to..... etc." Or, "As a 26 year old software from China my approach to the science may be a bit different than the usual western ....... " or Being a software engineer from China and only 26 years old I am uniquely poised to...."

You can't get around using pronouns but when you get used to using lots of different pronouns and prepositions so as not to sound too repetitious or like you are saying I, I, I, me, me, me all the time. I sometimes go back and change my writing in order to not repeat words too many times. 

Hope that helps! 

"I'm a 26 year old software engineer from China" (That cuts out 2)

Thank you Leigh Mumford and Dorothy.

 One way to avoid the repetitive use of "I"  is to discuss facts,   rather than yourself.

    It is possible to write continuously  without   any  references to "I" at all.

#1  When thinking about a subject,   remind yourself that your subject is an "it".

   Therefore,  avoid phrases like   "I think" or   "I intended" or   "I want to show"

or "I feel".   Such expressions do have their proper  place in communication,  but seldom need to

be used  in  certain  kinds of writing. Philosophy, Science,  Theology,  Law, History, Politics,  and Art are all subjects which can be written  about extensively  without ever using  "I"  for the subject of a sentence.

#2   Also,  rather than  write about your "experience" with a subject,   write about the experience of other people in regard to your subject.   For example, if you are discussing  an objective subject

(You would be an example of a subjective  identity.)

  Write about the written work of other people and quote them.

I agree with Leigh; native US English speaker.  You would combine the 3 sentences into one.  In English we have a saying less is more, especially in a professional settings.  So the more concise (ie. short and to the point), the better.
