Hello! I'm a native Indonesian speaker, and I am fluent in English. I had decent experience in the field of Indonesian-to-English or English-to-Indonesian translation.
In the past year, I had interned in the Foreign Affairs division of the East Java Provincial Government. There, I had been tasked to translate various correspondence letters and proposals. These includes letters addressed to the governor of East Java from ambassadors and other foreign diplomats. I had also translated various proposals, including several from Psychiatric Hospitals.
As such, I believe that I had enough experience to fulfill your English-to-Indonesian translation needs. If considered for your project, I would put in my best and finish up with the work within the stipulated time frame.
