Hi,
I have understood your requirements and have derived that I can help you with your requirements.
I’m an RoR senior developer and have a team under me which has been working on the technology for over 6 years now.
We also have knowledge about Selenium Webdriver and can test automation.
Let me know if you want to see our work or client referrals.
Will be happy to share our Github link, too.
Looking forward to hearing back from you.
