Hello,
I am currently working as the main developer of a Japanese Magento 2 store. I did their migration from Magento 1, developed few custom extensions for their needs (Japanese market is quite different) and I am maintaining it (performances, audit, bug fixing...). I can do few design changes but I am not a designer, so if your project involves a full redesign, I might not be the right person (I can install and customized themes though) but if not, I would love to discuss more details with you.
Regards,
Lionel
