Chat bot management service like flowxo.com for Facebook Messenger

NEED TO HIRE 2-3 Freelancers for part-time

I'm looking for a fullstack .NET developer (Russian and English speaking) to develop bot management service like flowxo.com, but only for Facebook Messenger. Please take a look at flowxo.com before applying, because code-logic may be quite complex and contain a lot of dynamic bindings.

There are four components to implement:
- Workflow engine
- Single page application
- WebAPI
- Facebook Messenger integration

For all of them there is a proof of concept, so you will have working examples to start from.

You will work with customer from Israel through Upwork.
Hourly rate is up to $10
$1500 / month

Technologies: C#, MVC, Angular 1x, MSSQL, EF
