is it right "i am trying to enter my step into corporate world by getting my first job, where i can implement my theriotical knowledge into practical way, which i have learned during my educational career.

I suggest:

I am trying to enter the corporate world by securing my first job. I hope to implement practically the theoretical knowledge which I learned during my education.

Note that the pronoun ā€˜Iā€™ is always capitalised, regardless of its position in a sentence.
