Pre-launch Technical Assurance Review for Lovable/Supabase Web Application

I'm looking for an experienced React/Supabase developer to carry out a focused pre-launch technical review of my application. Experience with Lovable is highly desirable. My goal is simply to launch with confidence. I'm looking for an experienced engineer to identify any significant technical risks that should be addressed before I put real users on the platform, rather than trying to achieve a perfect codebase. The application is a pre-launch React/TypeScript web app built using Lovable and Supabase. It includes authenticated users, role-based access, database records, file uploads, Edge Functions and transactional emails. The code is synchronised to a private GitHub repository. The application has already undergone independent penetration testing and remediation. This is not a request for another penetration test or a general code refactor. What I'd like you to review: Please review the current codebase and Supabase configuration for any significant technical risks that could affect: - security - authentication and authorisation - data integrity - reliability - recovery if something goes wrong In particular I'd like you to: - review the codebase for any significant implementation risks or architectural concerns that could cause problems in production - check that Supabase authentication and RLS appear to be implemented safely - identify any obvious issues with Edge Functions or privileged operations - check for exposed secrets or other configuration problems - review the current backup and recovery position, including GitHub, database, uploaded files and configuration, and explain clearly what is and isn't protected, together with any important gaps before launch - confirm whether the GitHub repository can be cloned and built independently of the Lovable editor, or identify anything that would prevent this. Existing security review A penetration test has already been completed, together with remediation work. I'll provide the existing reports so you can avoid repeating work that's already been done. Deliverables At the end of the review I'd like: - a plain-English assessment of whether the application is suitable for a small production launch, together with any issues that should be addressed beforehand - a prioritised list of any launch-blocking or high-priority issues - confirmation of what is and isn't currently backed up - any recommended pre-launch actions - confirmation whether the application can be built independently from the GitHub repository - a written report explaining all findings and recommendations in clear, non-technical language wherever possible, so they can be understood and acted upon by a non-developer - for each recommendation, please explain what the issue is, why it matters, how important it is, and whether it should be addressed before launch or can safely wait until later Out of scope This project is not intended to cover: - another penetration test - refactoring the application - adding new features - migration away from Lovable - performance or scalability planning If you identify issues that require implementation work, we can discuss those as a separate project. Please include in your proposal - examples of Lovable and Supabase projects you've worked on - confirmation that you've worked with React/TypeScript applications in production - your approach to reviewing backup and recovery I'm looking for practical, proportionate advice. Please focus on issues that materially affect security, reliability, recovery or maintainability, rather than minor coding-style preferences or theoretical improvements.
