exprience

Correct spelling is 'experience'

Experience - noun or verb
Experienced - adjective


I am experienced in ....
I am very experienced in .... (By the way, nothing wrong to add 'very' in front of experienced if you want to emphasize it)
I have the experience in ...
I have 10 years' experience in .....
(以上experience, experienced 等字都解作經驗)

I experienced hard time when I was in the hospital.
(以上experienced 這字解作經歷, 則較為貼切)

adj. expert

".............is an expert at/in/on.........."

1. 熟練的,老練的;有經驗的[(+at/in/on)]

Exuberance of exprience = 豐富的經驗

You can write: "I am experinced in ..."

You don't have to add the adjective "very"
which is redundant.

I am very experienced in ................
