Dear Madam, Sir,
After carefully reading your job posting, I am certain I can do it perfectly. I have a Master's degree in Information Technology and a very long experience in academic writing, translation, SEO and digital marketing.I was the manager of Google Developers Group in my city for three years which gave me very good communication, negotiation and technical skills.
I am a new freelancer, however, I am certain that you will be very pleased with my professional work, I am a native French speaker and I master English fluently.
Thank you for your consideration, Sincerely.
