Job description

Hey, we are making a random video chat.

We made the app in ios native.

The frontend is almost done.

However, we have a lot of problem in the backend.

Before I explain, let me explain the app. When the users register, they upload their video profiles.

There are 2 features (Random video chatting mode and selective video chatting mode)

1) In the Random video chatting mode:
In the random video chatting mode, the users get to see the randomly connected user's video profile. When the video chatting connection is established, they get on the video chat in p2p without going through the media server.

In the selective mode, the users can swipe through the video profiles who are online (using AWS S3 and CDN). if the user is offline, the video profile will be hidden. So basically, the video profiles will be shown to whom are online in real time.

Here are some problems that we are having:
1. connection problem. (setting up signaling server properly)
- When the users turns off or press the home button, it should be considered offline user and move to the next match or next video profile in the selective mode.
- When users switch from cellular data to wifi or wifi to cellular, the connection should not get lost.

2. Stability.
- There are many times when in the random mode, the video profiles play in a loop but doesn't get the video chatting connection.

3. Loading 4 video profiles in advance.
- We need this feature really bad. Also, we need a feature where it can show the thumbnail before the video profile starts.

4. Server logic for the location base and the estimated cost of the server.

5. Deploying signaling server in AWS using S3 and cloud front.

6. Storing data in the admin page. (In the admin page, it must have a screen shot of the misbehaved users when one reports the other user)

We are planning to hire full time backend developer in our office in Hanoi, Tu Liem, Mon City.
