This is fairly well-written, but there are several errors with phrasing, register and prepositions.
Response to email inqury about no technology background for a position
Dear XXX,
Thank you very much for your email. I understand that my qualifications have caught your attention and I would like to take this opportunity to briefly discuss my skills with you about my skills briefly.
"Discuss about" is a common error. No preposition follows <em>discuss</em>.
Regarding to your last question, yes, whereas I do not have a technological background for this position, but for certain I still strongly believe I can do this job well. This is not only because I have played a similar role in my previous working experience, coupled with and the strong organization and management skills, I have demonstrated which I can bring to this position but also with my having no relevant technological background can prove to be an advantage. as well as I will not take your offer of employment for granted to accept and will put more efforts towards compensating for this shortfall. I am a very diligent employee who sets high standards for myself in every position. I anticipate there being further discussion about how my experience applies in this position. I am looking forward to hearing from you.
The phrases you need are <em>In regards to...</em> or <em>Regarding..</em>. Beware of confusing the two!
Sentences need to be short and clear - remember that employers want workers who can communicate clearly and effectively. This means removing anything unnecessary: too much information can weaken your message.
Avoid spoken forms (like contractions - <em>I'm</em>) in formal writing.
"I wish" sounds like an unreal desire, ie. what you wish for probably won't happen.
Gerunds (<em>[verb]</em>ing) always follow the phrase <em>to look forward to...</em> This is unrelated to infinitive verbs.
Thank you very much.
Best Regards,
