Definite article (o)
‘o’ introduces the noun phrase ‘quanto’, acting like ‘the’ in English.

Here ‘quanto’ works as a relative adverb meaning ‘how much’, introducing a clause that describes the degree of helpfulness.
Ser vs. estar (sou)

✕Common Mistakes

If you want to ask someone else to show, you need the imperative ‘mostra-me’ or ‘mostra‑me’; without the pronoun it sounds like a statement.

‘Prestativo’ is correct for a male speaker; a female would say ‘prestativa’. Using the wrong gender sounds odd.

Cultural Tip
In Brazil, boasting about personal traits can be seen as playful banter among friends, but in more formal settings it may come across as arrogant. Adjust the tone based on your relationship with the listener. Also, the verb ‘mostrar’ (to show) is often used colloquially to mean ‘let me demonstrate.’
