Answer 1

I worked as a graphic designer in Poland in several companies for which designed the logos and slogans look <- tutaj nie lepiej użyć Present Perfect? :) : I have worked

Dalej,

I am a very conscientious and punctual PERSON, 

Następnie:

I would like to developed your skills in your company and take on new challenges.

Po 'would' podstawowa forma więc nie DEVELOPED tylko DEVELOPE.

 

Poza tym wydaje mi się że jest w miarę okej, chociaż szczerze to mi troszkę tłumacz google przypomina, mam nadzieję że jednak nie mam racji ;) 

 

 

 

 

Pozdrawiam

Answer 2

w pierwszej linijce dopisz do graphic słowo designer

for several companies zamiast in

I designed logos and slogans for them. zamiast kolejnej części zdania

po projects dopisz they, for example (nie ex ample)

which is zamiast that is (bez przecinka)

my zamiast his

I can communicate in english.

całkowicie usunąć "I'm sure it's good"

I also used this language working in Poland for foreign companies 

kolejna część zdania jest niezrozumiała dla mnie

I would like to develop my (nie your!)

I'm looking forward (dalej dobrze)
