Experienced dev to develop mask & filters for Existing React native short video app

Hello, I'm looking for someone who can help us with developing a module for applying masks & filters on an existing react native based video app project. The feature will enable users to shoot using phone camera and provide ability to apply filters to the users in real time similar to Roposo. These could include an integration of any exiting library of filters. Looking for the bids with best price from qualified people in the shortest time possible. It means that you should already be having a framework ready for such projects. The developer may have a bit longer association as we progress to develop custom filters and improve / include more workflows.
