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 web development, blogging, SEO and Social Media marketing. I have worked as a salesperson for two companies (from Malta and Sierra Leone). I was the manager and community manager of Google Developers Group in my city for three years which gave me very good communication, negotiation and public speaking skills.
My freelancer.com profile is new, however, I am certain that you will be very pleased with my professional work, I am a native French speaker and I master Arabic and English very fluently.
Thank you for your consideration, Sincerely.
