Mid Level RoR Developer

I am a Ruby on Rails developer with extensive 6 years of working experience in Software Development. My passion is to develop web applications to make the project usable and efficient. I write tests using RSpec, such as integration, unit and feature tests. I also do some product integration with other services. I'm doing some external requests using endpoints and receiving data from webhooks. Do the integration of different communication platforms such SendGrid, Twilio and Plivo APIs to send Email / SMS blasts to thousands of recipients, receive inbound SMS and connect phone calls to other mobile numbers.
