Lovable Expert: App Integration, Data Migration (from Bubble), and UI/UX Refinement

We are a property maintenance, painting, and cleaning company based in New York City (specializing in supplying labor for residential portfolios). We are looking for an expert developer in Lovable to unify our digital ecosystem, polish up the final details, and execute a delicate data migration. Currently, we already have two platforms built in Lovable: An internal application that our team currently uses to assign labor, manage orders, and oversee daily field operations. A new client-facing platform intended to replace our legacy system. Our legacy client system still lives on Bubble and is hosted on our main domain (brizacorp.com). We need to connect both of our Lovable apps into a "single ecosystem" and seamlessly transition our clients without friction. Key Responsibilities: Ecosystem Integration (The "Single World"): Connect the Lovable client platform with our internal team platform. Orders, job statuses, and oversight must sync perfectly in real-time (either by sharing the same backend/database or via robust APIs). Refinement & Polishing: Fine-tune the UI/UX of the client platform in Lovable, fixing minor details, improving user flows, and ensuring it is 100% production-ready. Data Migration from Bubble: Export all historical data (client profiles, user credentials, service records) from the old Bubble platform and import it into the new Lovable backend. Clients must be able to log into the new app and see their complete history intact. Production Deployment: Replace the Bubble application currently hosted on brizacorp.com with the new Lovable platform. Candidate Requirements: Proven, advanced experience working with Lovable and its backend structure (Supabase, Firebase, etc.). Solid technical background in exporting, structuring, and migrating relational databases, specifically moving away from Bubble. Ability to understand multi-app architectures that feed from a single unified database, particularly for field service and labor operations. When applying, please answer the following: Given that we already have two separate Lovable platforms (internal and client-facing), what would be your technical strategy to connect them so they share data in real-time? How would you handle the data export from Bubble to ensure that passwords and client history remain intact when moving to the new backend? Please share examples of complex applications or integrations you have built recently.
