Senior Supabase & RLS Specialist Needed for SaaS Multi-Tenant Security Audit

Project Overview: We are looking for an experienced Supabase & PostgreSQL Security Specialist to conduct a thorough security and performance audit for a multi-tenant SaaS platform ("EduPremium") managing educational academies. The system relies on Supabase for authentication and database management, utilizing Row Level Security (RLS) to enforce strict multi-tenancy and role-based access control. Key Responsibilities: Multi-Tenant Isolation Audit: Review and validate our PostgreSQL schema and RLS policies to guarantee 100% strict data isolation between different tenant academies. Role-Based Permission Check: Ensure financial data (pricing, profits, billing) and sensitive student/contact info are strictly restricted from non-admin roles (e.g., teachers and supervisors). Security & RLS Optimization: Identify any potential policy bypasses, performance bottlenecks, or recursive query risks within our existing RLS setup. Actionable Recommendations: Provide a detailed assessment report and, if necessary, refined SQL/RLS policy scripts to fix any security gaps. Requirements: Proven experience with Supabase, PostgreSQL, and advanced Row Level Security (RLS). Strong background in Multi-Tenant SaaS Security Architecture. Experience with database performance tuning and security auditing. Ability to deliver clear documentation and SQL fixes.
