Formattazione testo del curriculum

Buonasera,
vorrei se si potesse formattare il CV in modo più compatto, perché occupa più di due pagine, come posso fare?
Magari compattare lo spazio tra righe, o se dovessi anche il carattere.
Se cambio \documentclass[11pt,a4paper] in 10 ad esempio non avviene nulla. Devo inviare anche structure.tex, structure.sty?

Grazie per l’attenzione.

Vi mando il CV:

\noindent
I am a pragmatic and enthusiastic Computer Engineer that has amassed a wealth of experience in the creation and implementation of web based applications. I am able to utilise a large range of languages and tools, and can adapt to any new technologies with ease. Throughout my professional career I have managed and maintained numerous hardware's and software's. I have a quest for new knowledge and keep myself educated in the industry.
\\
\\
I speak multiple languages and I am currently in the progress of attending an English School (St Giles – British Council) to enhance my command of the English Language.
My interpersonal skills, combined with my language abilities, provide me with the platform to create strong professional relationships and my enthusiasm for the industry motivates a team. I collaborate effectively within a team environment, whilst maintaining the self-discipline to deliver independently. I am accustomed to dealing with numerous tasks simultaneously and can prioritise large workloads accordingly.
