Hello there,
I've read through your project description, and feel confident I can assist you in building your startup into a successful business.
I have over 12 years experience in the telecoms industry, I have worked with, developed and designed the network, and telephony systems for one of UK's top Ofcom licensed telecom providers (TTNC), I have also developed another smaller UK telecom provider (XoverX), and also developed for a telecom provider in Indonesia too (XipCall).
The above mentioned companies, offer hosted telephony solutions and services, as well as virtual numbers. I developed their entire telephony systems, and some of their web portals too, and the APIs to facilitate configuration of the customers' services. I also designed and deployed their network architecture too.
I hope I can be of help to your business.
I hope to hear from you soon.
Best regards,
Adnan
