We're looking for someone to make a backend for our app on AWS. We need to have twilio like chat but can't use the client sdk because the client will be built in flutter. So this needs to be built with a REST interface and WebSockets. There will also be a few endpoints needed for: -creating, searching, editing, and pulling up details of different objects -Uploading photo's -User auth -And the ability to send push notifications

Hello, how are you? I'm a senior web developer and I have rich experience in WebSocket and Rest api. I have developed chatting systems using Kurento server, Twilio, Socket.IO. And developed admin panel and rest api for pos system, rest api for landing system etc using Angular 5 and Python Django. If you want your own custom chatting system, we have to use Socket.IO. About push notification, we can use FCM or Socket.IO. I will give you perfect result as you want with high satisfaction. Let us discuss more via chat. Best regards. Thanks.

Hi, - We have designed and built complete AWS Architecture for various clients to achieve Fault Tolerance for their applications. This includes complete mapping of Route 53, implementation of Simple Storage Service S3, Load Balancing and implementation of Relational Database Management Service. - We have a vast experience in integrating and customizing REST APIs. Quick Question: - Do you have access to Twilio API? I have gone through the Twilio documentation. We'd be required to build an Endpoint connection between the API Server and your website. We offer you the following: - Integration of API to fetch and update data dynamically. As mentioned in the API documentation REST scripting will be exploited using PHP for this step. - Setting up parameters to ensure that the requests made to API server are getting the required information. - Connection test (including token-based tests) to authenticate the parameters necessary for all requests made to the API server delivers the desired result. - QA and testing to ensure there are no post-integration bugs. My name is Bill, and I am the Business Analyst at GOLPIK. We are a Web Design & Development company, based in Lombard, IL with a phenomenally talented team of designers and developers. Looking forward to working with you. Regards, Bill Walton Golpik Inc.
