Website code review

Hi Andrew I'm building ODOCK, a rental listings website where tenants will also submit rental applications (including SSNs and ID documents). It's built with Next.js and deployed on Vercel. The front end and backend are both finished and it's ready to deploy (current preview: vodock.vercel.app). I want to launch soon, and before real tenants start sending personal data, I'd like a human security and code review. Mainly: - Login and account security - Who can see applicants' SSNs and documents (access control) - File uploads - Any data leaks in the API (e.g. public endpoints exposing private fields) - Secrets or keys exposed in the front end I can share the full codebase as a zip or a private GitHub repo. Could you give me a fixed price (or an hour estimate) and how long it would take? Thanks, CEShlomo
