I will conduct a comprehensive full-system security audit, multi-tenant isolation logic, and fault tolerance of your KitchenOS platform at the Enterprise SaaS level (Next.js/Prisma/PostgreSQL).
How is tenant separation currently implemented at the Prisma architecture level (global tenant_id in all queries through middleware/Prisma extensions or manual filtering in each server action), so that within the Security block I can prioritize checking for end-to-end data leaks between commercial kitchens?
Tools (including custom automation scripts for emulating parallel POS sessions and API fuzzing), examples of my audits of complex SaaS systems, timelines, and budget will be discussed in private correspondence.
