We are looking for a developer with experience creating a branded SMS portal for sending and receiving SMS messages via multiple SMS gateway providers. Experience creating/integrating with SMS API vendors such as Trumpia, Nexmo, Flowroute, Twilio, SMS Gorilla or similar. Can be a portal you've previously created and customize for us or something created for us. We have various SMS agreements in place for inbound and SMS, but need the ability for automated responses, SMS queueing for agents and various other features to be added over time. See attached detailed requirements.
We want to get the basic functionality up right away, but add more enhanced functionality over the next month or so. We'd like a resource that can continue to do work for us in the future.
Automated responses is something we'd like within a couple of weeks if possible.
