I would like to pursue higher studies in my favorite areas to refine my knowledge and advance my skills thereby strengthening my academic proficiency.
This will be better if it says a few specific things. Maybe you should name your two favorite areas in this sentence...
Also, do not say "strengthen my academic proficiency," because you have more meaningful goals than that. Talk about becoming prepared for a particular kind of work that you intend to do.
As final year project, i was a member --- capitalize that I
Another typo: I hav enjoyed the experience
My idea for you: At least three times in the essay, mention the specific kinds of work you hope to do in the future and/or the specific courses you are most excited about. That is how you show your vision for the future.
