Hi,
I have a good knowledge of handling and maintaining SMPP connections with telecom provider for USSD and SMS services.
Your software can be a Desktop app, built with Windows Project Foundation (WPF) [Recommended],
A Cross-Platform Mobile Application built with Xamarin Form or
A Web Application built with ASP.Net Core WebAPI + Blazor. This depends on your preference.
Furthermore, there are 10 top features I will add:
1) I'll design an interface that will allow you to IMPORT phone numbers from various file/data formats like (Excel, CSV, and JSON).
2) I'll add an interface where you can manually insert specific numbers to send SMS to.
3) I'll create a backend or database setup to store counts and logs of sent messages.
4) I'll provide the ability to integrate custom or popular CRMs as a data source.
5) I'll provide SMS body and sender templates which can be re-used according to your requirements.
6) I'll set up a scheduler to enable automated or timed initiation of SMS sending.
7) I'll provide adequate code documentation and user manual.
8) I'll provide additional 1-month support after project completion for quick enhancements and corrections.
9) I'll provide security features to limit access to the app (if you require). This can be a login/password or another form of authentication.
10) All these will be delivered in 14 days. We can work on some few days to perform end-to-end tests.
I look forward to being interviewed by you.
Regards,
