I'm a freelance writer specialising in: - creative writing - ghostwriting - writing for children - educational materials (particularly primary school, or TEFL) - article writing - travel writing - editing and proofreading I graduated from Bath Spa University in 2011 with 1st class hons in Creative Writing and English, after which I spent five years living in Asia (China and Japan) where I was working as a freelance writer and TEFL teacher. These days I am a frequent contributor to several TEFL and travel websites. As an experienced language teacher, I specialise in working with those who use English as a second language. I also have much experience of materials with children as their target audience (as I have worked with many different textbooks during my time as a teacher, as well as making my own graded materials and specialising in writing for children during my time at University) and so any creative writing, editing or article writing to do with children would be my cup of tea. I pride myself in sticking to deadlines, working professionally and neither overselling nor underselling my abilities. I have an excellent command of the English language and also speak basic Chinese and Japanese. Contracts I love include: - writing stories for children, ghostwriting children's books and creating educational materials. Whether it's creating a modern version of a well-known folk story or creating original content on a chosen theme, ghostwriting for children is my specialist topic - writing colloquial, easy-to-read travel articles, especially with listicle features and awesome destinations (I specialise in Japan, China, and the UK - particularly my niche of the Channel Islands) - I'm always interested in long-term, professional contracts with top clients If you are interested in hiring me to help with your projects, please get in contact. I look forward to hearing from you.
