Lisa, nanny in Battersea SW11

Hello,
My name Lisa, came from Tokyo, Japan to London with Tier5 visa. (-18 April 2018)
To be honest, I do not have any qualification related to childcare, however, I have much experience of taking after children.
I have a lovely nephew and a niece. As my sisiter was busy to work a few years ago, I had looked after my nephew since he was born. I love children of course. In far future, I would love to involve in humanitarian aids or UN acitvities in somehow, but for now I would like to focus on commiting to children as working.
I'd appreciate it if you can have any interest in me to work.
My 1st language is Japanese and 2nd is English.
Thank you,
Lisa
