Chi sono
I'm a data analyst and BI professional with 7+ years of experience working with international teams, combined with advanced English skills built through years of professional collaboration with global companies. I also offer translation and proofreading services between English and Brazilian Portuguese, focusing on natural, accurate results rather than literal translations.
I'm detail-oriented, reliable, and committed to clear communication throughout every project. Whether it's a quick translation or an ongoing collaboration, I bring the same care and precision to every order.
