Hi, We currently provide clients with the ability to send SMS messages from a custom developed system connected to a software solution called ActiveXperts and e-mails using a software called ActiveCampaign. I'm looking for a developer that can integrate these current SMS and e-mail systems into one dashboard and add Chat and WhatsApp features to the solution. The system has to be multi-tenant and allow us to create resellers as well as direct clients. The basic idea is that we add credit to the client's account and they send either SMS, e-mails, WhatsApp messages, as well as have the ability to add a live-chat plugin to their site that they can control from their control panel. The candidate must have advanced skills working with SMS message providers, and have advanced experience working with SMS, e-mail and WhatsApp protocols. The system must also be bilingual, English and Spanish. If you have the knowledge and skills to get this done please contact me immediately.
