Hello,
My name is Raju and possess 2 years of massive experience in developing RoR apps. I have been building apps using :
* Ruby on Rails (1.9.3, 2.2.0, 2.2.3,4.2.3, 3.2.11, 4.2.5)
* RSpec, Cucumber
* MySQL, PostgreSQL, MongoDB, redis
* Amazon Web Services, Linode, Heroku
* HTML5, CSS, jQuery, Twitter Bootstrap, JavaScript, Ember, Ext, KnockoutJS etc.
I have gone through the requirements you listed and its making sense to me what you are looking to develop. I can develop a Ruby on Rails application to manage LoRaWan nodes.
I can also share you my past typical RoR based projects and can be a good match for this project.
I hope to have words with you soon.
Best regards,
Raju
