Hi,
Thank you very much for your job posting.
As a certified RoR devleloper and senior full stack web developer, I am so confident to implement your requirements.
I am also a certified DevOps engineer and I've worked wth Peatio several times. I've deployed twice it on AWS because I am also a certified AWS Solution Architect. Most of all my Rails projects have been deployed on AWS, but I can rails app on any VPS you prefer.
Hope to hear from you soon.
Regards,
Bidyashish
