Dear Sir/Madam,
I am a native Indonesian speaker who is proficient in English (CEFR Level C1/IELTS Band 8.0, last test in April 2021). Currently, I have plenty of time since I have left my previous job and still looking for a new job; hence, my schedule is very much flexible. I also possess an experience of being an interpreter (English to Indonesian and vice versa) for some Singaporean teachers who came to educate Indonesian children. Therefore, I am confident that I can effectively assist you in this project.
Thank you for your time and consideration. I look forward to receiving your response.
Yours faithfully,
Jonathan Tanusaputera
