Loveable website conversion

Hello, I have recently vibe coded a website on loveable and will need to convert to a more stable and well performing site. The website is a delivery service for content creators, where users send "Delivery Rooms" to clients full of media. The user is given a dashboard where they can create delivery rooms, upload content and send to clients, this website is competing with google drive, wetransfer, etc. The website is in early stages at the moment. It will have frontend and backend load, with virtual storage, automated emails, new features rolling out for updates. The website is in a closed beta being tested by users now, hosted from loveable. However with large scaling I would need a custom and well optimized version. Thanks
