    I'm looking for a Full-Stack Developer, but maybe someone who has a bit more interest in the backend. Essentially, we had a working prototype with Angular/Bootstrap and Firebase and we are modernising it, starting with fresh designs and fresh code. We have great designs, all done in Figma and now it's time to implement them. As we had a working prototype, the DB structure and functions are largely done, but now is the time to rethink our approach, so the first step will be to map out the DB structure and plan out our backend API (as inevitably we will use it as well in a React Native app down the road)...

    Hey there. I would like to develop a small platform, where users can select one or many images from their phone gallery and upload them to the backend cloud storage, and then an editor will make an edited video using those images and upload the video to the cloud server which will be shown under "My Videos" in the user's mobile app. 1. System should automatically assign the editing task to one of the editors based on the number of tasks they currently have. 2. Users must create an account, and editors will be added manually to the system. 3. Users will receive a notification when their edit is ready to download. Please tell me if you can handle this project, and what will be the cost and time required for this project. Thank you.
