ASP.NET Core MVC and Xamarin Expert - LongTerm (Should work on my PC)

Hi. I have a project already built using ASP.NET Core MCV and Xamarin (Web and mobile version). I need to add and improve some features. The Technologies Used: - DB: Microsoft SQL Server - Application: ASP.NET MVC, ASP.NET WebApi, .NET Entity framework, CSS, Bootstrap, Javascript, JQuery, - Leaflet with OpenStreet Map, momentJS - Mobile native app: Xamarin - Native Notifications: Firebase Cloud Messaging (FCM) Deployment components: Web API – responsible for all logic in application: - read and store data from\to database, - data validation - processing data (like processing phone contacts list) - send notification via FCM - send SMS via SMS gate Web Application – prepare views for the user. Communicates with Web API via REST and renders data as ASP.NET HTML pages. Native apps - Native app works as a client/hosting environment to web application. Native app for Android and iOS is built using Xamarin. Web application is embedded in native app as a WebView. All bidirectional communication between WebView and native App using javascript App use external SMS provider to send SMS for invited users, account activation and password recovery. Please bid if you are an Expert!!! Thanks
